Answer:
x=29
Step-by-step explanation:
3x-13=74
We want to solve for x, so we need to isolate it.
The first step is to add 13 to each side.
3x-13+13=74+13
3x = 87
Then we divide by 3 on each side
3x/3 = 87/3
x= 29
Answer:
this angle is a right angle(90°)
and one of the 2 angles is 30
3x+30=90
3x=90-30
3x=60
x=20
==> B
The 3 is distributed to the a+b inside the brackets........
