Answer:
-3 + x^2
Step-by-step explanation:
8+x^2-11
First combine the like terms.
so..
8-11 = -3
= -3 + x^2
but we don't know the value of x so we just leave it as it is.
And they both are not like terms so we cant solve them together so you stop there
Hope that helped!
Answer:
x=10
Step-by-step explanation:
It's a 90 degree angle.
90-60=30
30=the remaining angle, 3x
x=30/3, or 10
Hope I helped!
Answer:
C. 55°
Step-by-step explanation:
The computation of mAC is shown below:
Given that
Diameter AB would be parallel to CD
McD = 70
Based on the attached diagram and the above information
mAC is
= (180 - 70) ÷ 2
= 55 degrees
hence, the correct option is third
