Answer:
46°
Step-by-step explanation:
Points of note
two angles are complementary in a right trianglesin 44° = cos x°Solving
The first thing to understand is "complementary" means that the two angles add up to 90°Therefore, 44 + x = 90x = 46°Answer:
46°
Step-by-step explanation:
Complementary angles
Two angles whose measures sum to 90°
In a right triangle, the angle opposite the hypotenuse is always 90°.
The interior angles of a triangle sum to 180°, therefore the other two angles are complementary angles since their sum is always 90°.
So we can label one angle as [tex]x[/tex] and the other as [tex](90-x)[/tex].
The side opposite angle [tex]x[/tex] is the side adjacent to angle [tex](90-x)[/tex].
Therefore, using trig ratios, we can say that [tex]\sin(x) = \cos(90-x)[/tex]
So, if [tex]x=44[/tex] then:
[tex]\implies \sin(44) = \cos(90-44)=\cos(46)[/tex]

A pet store has 11 puppies, including 5 poodles, 3 terriers, and 3 retrievers. If Rebecka and Aaron, in that order, each select one puppy at random without replacement, find the probability that Aaron selects a retriever, given that Rebecka selects a poodle.
Answer: 0.2066
Step-by-step explanation:
Probability of Rebecka selecting a poodle = 5/11
Probability of Aaron selecting a poodle = 5/11
Both select one puppy at random with replacement, so their choices are independent.
Thus, probability that both select a poodle = [tex](5/11)\times(5/11)[/tex]
[tex]= 25/121 \approx 0.2066 \ $or 20.66\%[/tex]

if x-y = -10 and x-y = 2 what is the value of x
Answer:
x = -4
Step-by-step explanation:
x+y = -10 or y = -10 - x
substitute this into the second equation
x - y = 2
x - (-10-x) = 2
2x + 10 = 2
2x = -8
x = - 4

Jim can't remember the last digit of his best friend's phone number. He plans to just dial the number and guess the last digit. What's the probability that he'll dial the correct number in the first 2 tries?
a) 1/10
b) 1/45
c) 17/10
d) 1/5
e) 2/5
Answer:
D.
Step-by-step explanation:
1) the required probability can be calculated as sum of two probabilities:
P=p1+p2, where p1 - when the 1st attempt is correct, p2 - when the 2d attempt is correct;
2) p1=1/10; p2=1/9, then the required probability:
P=1/10 + 1/9 ≈ 1/5.

Question 2
Do the side lengths form a Pythagorean triple?
Answer:
Soln:
Step-by-step explanation:
Here,
Base(b) =9
Opposite/Perpendicular (p)= x
Hypotenus (h) = 24
We know,
(p)^2 = (h)^2 - (b)^2
(x)^2 = (24)^2 - (9)^2
x^2 = 576 - 81
x^2 = 495
x = root under 495
Answer:
1- 22.2486 2- No
Step-by-step explanation:
1:
[tex]b = \sqrt{ c^{2}- a^{2}[/tex]
C is the hypotenuse, or longest side of the triangle (24).
A is the one length we have besides the hypotenuse(9).
[tex]b = \sqrt{ 24^{2}- 9^{2}[/tex]
b = 22.2486
2:
No, because if it was a Pythagorean triple, it would follow the equation [tex]a^{2} +b^{2} =c^{2}[/tex].
[tex]9^{2} + 22.2485^{2} \neq 24^{2}[/tex].

You have a
3/8 chance of winning a scholarship. What are the odds you will get the scholarship?
The 3/8 chance is the probability of winning a scholarship.
The odds of winning a scholarship is 3/5
How to determine the odds?The probability is given as:
P(Win) = 3/8
The odds is calculated using:
Odds = P(Win)/[1 - P(Win)]
This gives
Odds = 3/8/[1 - 3/8]
Evaluate the difference
Odds = (3/8)/(5/8)
Evaluate the quotient
Odds = 3/5
Hence, the odds of winning a scholarship is 3/5

Find the diameter of O o. A line that appears to be tangent is tangent. 14 25
Answer:
•SEE BELOW•Let the diameter be represented as x.
Let the diameter be represented as x.Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:
segments would be:(14 + x)(14) = 25^2
segments would be:(14 + x)(14) = 25^2196 + 14x = 625
segments would be:(14 + x)(14) = 25^2196 + 14x = 625Subtract 196 from each side
14x = 625 - 196
14x = 625 - 19614x = 429
Divide both sides by 14
Divide both sides by 14x = 429/14
Divide both sides by 14x = 429/14x = 30.6
Divide both sides by 14x = 429/14x = 30.6Diameter = 30.6
