The area of the base is given by:
A1 = (1/2) * (15) * (13)
A1 = 97.5
The area of the lateral faces is given by:
A2 = (1/2) * (15) * (10)
A2 = 75
Then, the total surface area is:
A = A1 + 3A2
Substituting values:
A = 97.5 + 3 * (75)
A = 322.5
Answer:
The surface area of the equilateral triangular pyramid is:
C) 322.5 in2
Answer:
1.8
Step-by-step explanation:
Answer:
x = - 12
Step-by-step explanation:
∠ FCD + ∠ BCF = ∠ BCD , substitute values
x + 41 + x + 78 = 95 , that is
2x + 119 = 95 ( subtract 119 from both sides )
2x = - 24 ( divide both sides by 2 )
x = - 12
