Last question of the unit test​

Step-by-step explanation:

Take angle A as reference angle

using sin rule

sin A=opposite/hypotenuse

sin A=10/13

sin A=0.76

0.76=49.46 degree

A=49.5 degree

i got 86 for this

hope this !

if you need an explanation just ask

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
