QUICK! What is the surface area of the triangular prism?

88 ft^2

Step-by-step explanation:

The triangular face is that of an isosceles triangle, where two sides are equal. The formula for the S.A of a triangular prism is:

SA = bh + (s1 + s2 + s3)H

s1 + s2 + s3 are just the sides. This means you are finding perimeter.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
