Answer:
AT = 8
Step-by-step explanation:
Using the sine ratio in the right triangle
and sin45° = 
sin45° = 
= 
= 
Multiply both sides by AT
AT × sin45° = 8, that is
AT × = 8
Multiply both sides by
AT = 8
Answer:
-50 - 15y
Step-by-step explanation:
-5 ( 10 + 3y )
First distribute the -5 by multiplying it by 10 and 3y
(-5 x 10) + (-5 x 3y)
Than simplify
(-50) + (-15y)
Adding a negative is like subtracting a positive so you can turn (-50 + -15y) into (-50 - 15y)
Than you have your answer
-50 - 15y
