Could someone explain? i will give brainliest thank you

A

Step-by-step explanation:

Using the sine ratio on the right triangle on the right to find x

sin30° = = ( multiply both sides by 70 )

70 × sin30° = x , thus

x = 35

-----------------------------------------------

Using the sine ratio on the right triangle on the left to find y

sin42° = = = ( multiply both sides by y )

y × sin42° = 35 ( divide both sides by sin42° )

y = ≈ 52.3 ( to the nearest tenth ) → A

y = 52.3.

Step-by-step explanation:

Consider the larger triangle on the right:

sin 30 = x / 70

x = 70 sin 30 = 70 * 0.5

= 35.

So, considering the small triangle:

Sin 42 = 35/y

y * sin 42 = 35

y = 35 / sin 42

y = 52.3.

42%

step-by-step explanation:

we know,

total people = 60

total males = 25

percentage of males

= 25/60 × 100

= 25/6 × 10

= 25/3 × 5

= 125 / 3

= 41.

rounding of = 42%
