Answer:
Area = 24.54
Step-by-step explanation:
two sides have lengths 5 and 13.
Let the two sides be;
a = 5
b = 13
The angle between them is 49
C = 49°
Let the third side be c
Thus, using cosine rule, we can find the side c.
c² = a² + b² - 2ac•Cos C
Plugging in the relevant values, we have;
c² = 5² + 13² - 2(5 × 13)Cos 49
c² = 25 + 169 - 130(0.6561)
c² = 108.707
c = √108.707
c = 10.43
Since we now have 3 sides, from herons formula, we can find the area;
Area = √[p(p − a)(p − b)(p − c)]
Where p is half of the perimeter = (a + b + c)/2 = (5 + 13 + 10.43)/2 = 14.215
Thus;
Area = √(14.215(14.215 - 5)(14.215 - 13)(14.215 - 10.43))
Area = √602.4
Area ≈ 24.54

Answer:
120 degrees.
Step-by-step explanation:
All the angles in a triangle add up to 180. You have two of the angles given:
50 degrees and 70 degrees
To find the third angle of the triangle (BAC), use the expression:
180 - (50 + 70)
180 - 120
60
So, the third angle in the triangle is 60 degrees. Looking at angle DAB, you can see that it forms a straight line with angle BAC. A straight line is 180 degrees. Since we know BAC is 60, and BAC + DAB = 180, by doing 180 - 60, you can see that angle DAB is 120 degrees.

SIMPLIFY IT PHOTO IS UP I WILL MARK IT BRAINLIEST
Step-by-step explanation:
Notice that
9y² - 4xy + 4x²/9 = (3y - 2x/3)².
Therefore (9y² - 4xy + 4x²/9) / (3y - 2x/3)
= (3y - 2x/3).
Answer:
(9y²-4xy+4x²/9)/(3y-2x/3)
={(3y)²-2(3y)(2x/3)+(2x/3)²}/(3y-2x/3)
=(3y-2x/3)²/(3y-2x/3)
=(3y-2x/3)
(3y-2x/3) is the right answer.how to i find the lowest terms of a ratio 12 minutes to 3 hrs ?

N= 17 and P=0.8 is it suitable to use a normal distribution
Answer:
Since n(1-p) < 10, it is not suitable to use a normal distribution.
Step-by-step explanation:
Suitability of the normal distribution:
In a binomial distribution with parameters n and p, the normal approximation is suitable is:
np >= 10
n(1-p) >= 10
In this question, we have that:
n = 17, p = 0.8. So
np = 17*0.8 = 13.6 -> Ok
n(1-p) = 17*0.2 = 3.4 -> No
So, since n(1-p) < 10, it is not suitable to use a normal distribution.

to advertise o radio,the radio station charges 32naira for the first 10 words and 2naira per word for every additional word.how much will it cost to place an advertisement of 68 words on radio?
Answer:
Cost for 68 words = 148 naira
Step-by-step explanation:
Given that:
Cost of first ten words = 32 naira
Cost of additional words = 2 naira per word
Let,
x be the number of additional words.
y be the total cost
y = 2x + 32
We have to find the cost for 68 words.
The cost of first 10 words will be 32 naira.
Additional words = 68 - 10 = 58 words
Putting x = 58 in the equation
y = 2(58) + 32
y = 116 + 32
y = 148
Hence,
Cost for 68 words = 148 naira

Angle AOE has what measurement according to the protractor?
Answer:
140
Step-by-step explanation:
PENN
Hence angle AOE has a measure of 120 Degrees.
What is an Angle?An angle is a combination of two rays (half-lines) with a common endpoint.
How To Solve:When an angle is formed or drawn or opened clockwise , then we measure it using the upper scale of the protractor , and if the angle or its arc goes anticlockwise , we measure it using the bottom scale of the protractor.
According to the figure , the angle has been opened anticlockwise.
(Observe carefully , AOB , then AOC , AOD and so on. Suppose that O is the center of a clock and OA is the needle which is moving anticlockwise from position OA, OB, OC and so on).
So we will use the bottom or lower scale of the protractor. Line Segment OE of angle AOE is bisecting the Lower scale of the protractor at 120 degrees.
Hence angle AOE has a measure of 120 Degrees.
