Plz only answer if you know :(

x = 8.6 cm

Step-by-step explanation:

Reference angle = 35°

Opposite side length = x

Hypotenuse = 15 cm

Apply trigonometric ratio to find x

Thus:

Multiply both sides by 15

8.60364654 = x

x = 8.6 cm (nearest tenth)

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
