Answer: x = 11 degrees
Step by step explanation:
Triangle rule states that all angles of a trundle must equal to 180 degrees. So we have two known angles, therefore we can subtract them from the 180 degree total.
180-109-43
=28
Now to solve for x we have the equation
4x-16=28
We add 16 to both sides to isolate x
4x=44
Now we divide each side by 4 to get rid of the coefficient
x=11
I might not be right but a is 2 and b is 16
Step-by-step explanation:
The two choices hat I think are correct are 9 or 10
Answer:
the area is 60
Step-by-step explanation:
Triangle area fourmula is (h*b)/2
8*15=120 120/2=60
A=60
