Answer:

37.5°, 52.5°

Step-by-step explanation:

Let the two angles be 5x and 7x

Total ratio= 5+7 =12

5x = (5/12) ×90° ( sum of complementary angles = 90°)

= (5/2)×15°

75/2= 37.5°

Similarly

7x = (7/2)×15°

=105/2= 52.5°

<h3>Verification</h3>

37.5°+52.5°=90° (sum of complementary angles= 90°)

Write 0.624 as a percent and as a simplified fraction.

Doss [256]

Okay to find the percent version of 0.624 you multiply by 100. 0.624×100=62.4%. Now as a fraction the last number behind the decimal is in the thousandths place so put 624 over 1000. 624/1000 simplified it would be 78/125

What is the measure of angle A please HELP I’ll give you BRAINLIEST

k0ka [10]

Answer:

Option (3)

Step-by-step explanation:

By applying cosine rule in the triangle ABC,

BC² = AC² + AB² - 2(AC)(AB)cosA

5² = 3² + 7²- 2(3)(7)cosA

25 = 9 + 49 - 42cos(A)

25 = 58 - 42cos(A)

cos(A) = $\frac{33}{42}$

A = $\text{cos}^{-1}\frac{11}{14}$

A = 38.21°

A ≈ 38°

Option (3) will be the correct option.
