Two angles of a triangle add up to 65°. What is the measure of the third angle? 115° 295° 25° 55°
Answer:
115 degrees
Step-by-step explanation:
The third angle will measure 115° so option (A) will be correct.
What is a triangle?The three-sided shape known as a triangle is sometimes used to allude to it. Every triangle has three sides and three angles, some of which might be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
Sum of all three internal angles of the triangle = 180°
Sum of two angles + third angle = 180°
Given that,
Two angles of a triangle add up to 65° so
65° + third angle = 180°
Third angle = 180 - 65°
Third angle = 112°
Hence the third angle will be 112° measure.

A)
(3, 3)
B)
(5,2)
C)
(-2,1)
D)
(1,-2)
Answer:
5,2
Step-by-step explanation:
Here, we want to find the point that is a solution to the system of inequalities
From what we have, the points that lie in the dark brown patch represent the solution to the system
Hence the coordinates lying in these parts are the solution to the system
An example of such coordinates is the point (5,2)
Alyssa plans to spend AT MOST $230.00 on a new wardrobe. The skirts x
she wants to buy cost $15 each, and the shirts y cost $10 each. Write an
inequality that represents the number of skirts and shirts Alyssa can buy. *

Given
Total spending =$230
The cost of the skirt is $15
The Cost of the shirt is $10
Suppose she buys x skirts and y shirts
So, sum of the spending on skirts and shirts must be less than or equal to the $230

Reina and Sam are multiplying (84)5 (73)9.
Reina's Work Sam's Work
(84)5 (73)9 = 84 + 573 + 9 = 89712 (84)5 (73)9 = 84⋅573⋅9 = 820727
Is either of them correct? Explain your reasoning.
Answer: So Reina and Sam are multiplying (84)5 (73)9 and their work are (84)5 (73)9 = 84 + 573 + 9 = 89712 Reina's (84)5 (73)9 = 84-573-9 = 820727
So Sam's Actually they are doing or multiplying using exponents. Reina's work (8*)s(7³)º=8*+5+ 73+9= 8° 712 This is incorrect because she added exponents instead of multiplying exponents Sams work (8*)5 (7³)º=84x5 73x9= 820 727 This is correct because Sam multiplied exponents correctly Exponents are multiplied not added.

The graph shows the function f(x) = 3^x. What is the value of f ^–1 (x) at x = 3?
The value of the inverse function f⁻¹(x) at x = 3 is 0.631.
What is an inverse function?The inverse function is defined as a function obtained by reversing the given function.
The function f(x) = 3ˣ is a one-to-one function, which means it has an inverse function denoted by f⁻¹(x).
To find the value of f⁻¹(x) at x = 3, we need to solve the equation f(x) = 3ˣ = 3 for x.
3ˣ = 3
Divide both sides by 3:
3ˣ/3 = 3/3
Simplify:
3ˣ-1 = 1
Take the natural logarithm of both sides:
ln(3ˣ-1) = ln(1)
Simplify:
ln(3ˣ-1) = 0
Now we can solve for x:
ln(3ˣ-1) = 0
3ˣ-1 = e⁰ = 1
3ˣ = 2
x = log₃(2)
So, f⁻¹(3) = log₃(2) ≈ 0.631.
Therefore, the value of f⁻¹(x) at x = 3 is 0.631.

Answer: Choice C) 6x+5y = -20
You have the correct answer. Nice work.
=================================================
Work Shown:
y = (-6/5)x - 4
5y = 5*( (-6/5)x - 4 )
5y = 5*(-6/5)x - 5*4
5y = -6x - 20
6x+5y = -20
-----------
Explanation:
In the second step, I multiplied both sides by 5 to clear out the denominator. Two steps later (step 4), we have 5*(-6/5)x turn into -6x, so the fraction goes away.
In the last step, I added 6x to both sides to get the equation into standard form Ax+By = C. In this case, A = 6, B = 5, and C = -20.
A radio tower is located 275 feet from a building. From a window in the building, a person determines that the angle of elevation to the top of the tower is 37 and that the angle of depression to the bottom of the tower is 35 . How tall is the tower?
Answer:
399.8 feet
Step-by-step explanation:
Since the angle of elevation of the top of the tower from the building is Ф = 37°, and the distance between the tower and the building is x = 275 feet. Let the upper part of the tower be h. These three components from a right-angled triangle with opposite side = h and adjacent side = x. So, by trigonometric ratios,
tanФ = h/x
h = xtanФ
= 275 feet × tan37°
= 275 feet × 0.7536
= 207.23 feet
Also, the angle of depression of the bottom of the tower from the building is Ф' = 35°, and the distance between the tower and the building is x = 275 feet. Let the lower part of the tower be h'. These three components from a right-angled triangle with opposite side = h' and adjacent side = x. So, by trigonometric ratios,
tanФ' = h'/x
h' = xtanФ'
= 275 feet × tan35°
= 275 feet × 0.7002
= 192.56 feet
So, the height of the tower, H = h + h'
= 207.23 feet + 192.56 feet
= 399.79 feet
≅ 399.8 feet

The sum of two numbers is 51.
The difference of the same two numbers is 9.
What are the two numbers?
Answer:
21 and 30
Step-by-step explanation:
x + y = 51
x - y = 9
add the two equations and y's will cancel out
2x = 42 divide by 2
x = 21 so put 21 in for x in the top equation and solve
21 + y = 51
y = 30
