Answer:
90°
Step-by-step explanation:
sum the parts of the ratio 2 + 6 + 8 = 16
The sum of the 3 angles in a triangle = 180°
divide 180 by 16 to find the value of one part of the ratio.
= 11.25° ← 1 part of the ratio
8 parts = 8 × 11.25° = 90°
The largest angle in the triangle is 90°
The simplified form is: =4p2−18p+8
Step by Step:
(4p−2)(p−4)
=(4p+−2)(p+−4)
=(4p)(p)+(4p)(−4)+(−2)(p)+(−2)(−4)
=4p2−16p−2p+8
=4p2−18p+8
For this case we have by definition, that the total surface area of a regular pyramid with a square base is given by:
Where:
p: It is the perimeter of the base
S: It's the inclination
It is the area of the base
Substituting:
ANswer:
Option B
There are thirty seven seats in total.
