the surface area is 136
you need to subtract the surface area of the base. It is a square pyramid, so both the sides are 4 inches, meaning you need to multiply 4x4 which is 16 and subtract it from the rest of the area. 136-16=120
There are four identical triangles that have identical surface area because it is a square triangle. So you can divide 120 by four to get the area of one of the triangles. 120/4=30
the formula for the area of a triangle is 1/2 base x height. We know that the base is 4 because that is the length that was given to us. so we can plug in our numbers into the formula
30=1/2(4)(height)
30=2(height)
and from there we can solve. 30/2=15
the height of the triangle is 15, which is also the slant height
to check our work, 1/2(4)(15)=30
4x15=60
1/2x60=30

Answer:
4x^2 − 4x −1 + 11 / x+1
Step-by-step explanation:
The answer is
4x^2 − 4x −1 + 11 / x+1
According to trignometery
If we take AB base and AC perpendicular
Then we can apply
Cos(45) = AC / 11
0.7071 = AC/11
0.7071 × 11 = AC
AC = 7.78
