Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
Answer:
f(3) = 9
Step-by-step explanation:

Answer:
a = 3.2
Step-by-step explanation:
2( -a - 8) + 7a = 0
-2a -16 + 7a = 0
5a - 16 = 0
5a = 16
a = 16/5
a = 3.2
hope it helps you!!!!!!!!!!
This expression would equal to 8.
