Find the surface area. Show work.
2 answers:
Hi there i just finished learning this!! anyways here’s the solution for the problem i also drew it as a net incase you’re a visual learner:) here is the formula for finding the area of a rectangle and a triangle if you need it:
: A=bh x height
rectangle: l x w=A
since a triangular prism is made up of 3 rectangles and 2 triangles, add up the answers of their multiplied numbers and it equals the SA. (total SA of you problem is 746)

According to law of cosines the length of RQ can be written as .
Given the length PR is 6 , the length of RQ is p, the length of PQ is 8 and the angle RPQ is 39 degrees.
A length of the triangle can be written as according to law of cosines if sides are given and one angle is
We have to just put the values in the above equation.
as .
p is the side opposite to angle given , the length of other sides are 6 and 8 and angle is 39 degrees.
Hence the side can be written as according to law of cosines if the angle is 39 degrees is as .
