Its would need to be 4 foot which makes a 90 degree angle and the top would have to be at a 35 degree angle i think
Answer:
The exterior angle to the vertex P, measuring 90°
Step-by-step explanation:
The sum of the internal angles of any triangle needs to be equal 180 degrees. So, we can write two equations:
mP = mQ + mR
mP + mQ + mR = 180°
Substituting (mQ + mR) by mP in the second equation, we have:
mP + mP = 180°
mP = 90°
this right angle is the bigger angle in the triangle, because the sum of all three angles needs to be 180°.
Each exterior angle is the supplementary angle of the respective internal angle, so the bigger the internal angle, the smaller the external angle.
So if the bigger internal angle is mP = 90°, the smaller exterior angle is 180 - 90 = 90°.

I'ma help you ok? c:
ok so first you do:
Area of a triangle A = 1/2bh
Area of a rectangle A = lw
then you do
Surface area of triangular prism SA = bh + (s1 + s2 + s3)H
I hope this helps you :)
Answer:
discount = 9
new price = 36
Step-by-step explanation:
The discount is the price times the discount percent
45 * 20%
Change to decimal form
45*.20
9
The new price is the original price minus the discount
45-9 = 36
