Answer:
x = 29
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
3(x + 2) + 52 + 35 = 180
3x + 6 + 52 + 35 = 180
3x + 93 = 180 ( subtract 93 from both sides )
3x = 87 ( divide both sides by 3 )
x = 29
Answer:
Volume = 80 in³
Step-by-step explanation:
The formula for volume of a pyramid is;
v=(A*h)/3
where
A=Area of triangular base
h=height of pyramid
Finding area of triangular base;
A=1/2*b*h
A=1/2*10*6=30 in²
Finding the volume
v=(A*h)/3
v=(30*8)/3=80 in³
