Part 1)

Part 2)

Part 3)

Step-by-step explanation:

Part 1) Find AC

we know that

In the right triangle ABC of the figure

Applying the Pythagorean Theorem

substitute the given values

Part 2) Find the measure of angle A

we know that

In the right triangle ABC

----> by TOA (opposite side divided by the adjacent side)

substitute the values

using a calculator

Part 3) Find the measure of angle C

we know that

In the right triangle ABC

----> by complementary angles

substitute the given value

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10
