Answer:
The value of x is 6
Step-by-step explanation:
we know that
If two angles are supplementary, then their sum is equal to 180 degrees
so
In this problem
m∠C+m∠E=180°
we have
m∠C=112°
m∠E=(3x+50)°
substitute and solve for x
112°+(3x+50)°=180°
3x+162=180
3x=180-162
3x=18
x=6
solution again.
Isolate the a. Note the equal sign. What you do to one side, you do to the other.
Add 5 to both sides
-5 (+5) + 1/5a = 4 (+5)
1/5a = 9
Isolate the a. Multiply 5 to both sides
(5)(1/5)a = 9(5)
a = 9 x 5
a = 45
45 is your answer for a.
