Answer:
$2950
Step-by-step explanation:
Add together the following three items:
Materials: $2000 plus 15%, or 1.15($2000), or $2300
Labor: $500
Equipment Rental: $150
Total: $2300 + $500 + $150 = $2950
Answer:
180° - 62° = 118° 118° ÷ 2 = 59°
This is the measure of each of the two base angles.
Step-by-step explanation:
Each face of a given pyramid is an isosceles triangle, with a 62° vertex angle.
Recall that an isosceles triangle has only 1 vertex angle.
- An isosceles triangle is one with 2 equal sides. Recall the Base Angle Theorem which states that in an isosceles triangle, the congruent sides have or produce congruent angles. This results in 2 equal base angles, in the regular case.
- The third angle is the vertex angle.
- To derive base angles from a vertex angle, subtract the value of the vertex angle from 180°. Divide the answer you get by 2. This is the value of each base angle.
- Remember also; the sum of all angles in a triangle must = 180°
180° - 62° = 118° 118° ÷ 2 = 59°
This is the measure of each of the two base angles.
