Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
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
258 = 240 + 18
258: 6 = (240 + 18) : 6 = 240 : 6 + 18 : 6 = 40 + 3 = 43
Your answer is 43.
