Take 49 and divide it by 7 and you get 7. 7 times 10 is 70. Your answer is $70.
Since the measures of the two angles are in the ratio 8:1, this means the bigger angle's is 8x and the smaller angle is x. Since they are complementary, they add to 90°, so you create the equation 8x+x=90°. This can be simplified to 9x=90°. Then, you divide 90 by 9 to get 10. This means x=10. Next, you replace x with 10 to find the measure of the bigger angle. 8x10=80, so the larger angle is 80°.
Step-by-step explanation:
Given,
Side of a square = 4xy
Therefore, area of the square = side × side
= 4xy × 4xy
X = 69o
2x + 42 = 180
=> x = 69
