Answer:
Step-by-step explanation:
<u>Area formula for equilateral triangle with side a:</u>
<u>The base area is:</u>
The three lateral surfaces have same sides of 10, 10 and 12.
<u>Find each surface area using heron's formula:</u>
- s = P/2 = (10 + 10 + 12)/2 = 16
- s - a = 16 - 10 = 6
- s - b = 6
- s - c = 16 - 12 = 4
<u>Total surface area is:</u>
Correct choice is C
-3

Consider this option:
1. given: n(A;B;C)=n(-5;-4;-1) and A(-1;-5;-2)=A(x₀;y₀;z₀).
Common view of equation for a plane is Ax+By+Cz+D=0, where A,B,C,D - numbers.
2. from another side using coordinates of A and normal vector it is possible to make up the equation: A(x-x₀)+B(y-y₀)+C(z-z₀)=0 ⇒ -5(x+1)-4(y+5)-(z+2)=0; ⇒ -5x-4y-z-27=0 or 5x+4y+z+27=0.
