What is the surface area of the rectangular pyramid shown? 59.5 cm2 63 cm2 75.5 cm2 99 cm2
2 answers:
Answer:
Option D.
Step-by-step explanation:
In this question figure of pyramid is attached below the question .
Surface area of the rectangular pyramid :
Area of the Base = Length × Width
= 10 × 2 = 20 cm²
Area of Lateral #1 =
=
= 31.5 cm²
Area of Lateral #2 =
=
= 8 cm²
Surface area of the pyramid = 20 + 2(31.5) + 2(8)
= 20 + 63 + 16
= 99 cm²
Surface area of the pyramid is 99 cm²

Answer:
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [7x + 1]° + [6x - 6]° + 55°
180° = [−5 + 13x]° + 55°
180° = [50 + 13x]°
-50° - 50°
____________
You then plug this back into all three expressions to get 71° as the measure of ∠G and 54° as the measure of ∠T.

Use the Pythagorean Theorem: 
You can do this because when you cut the rectangle in half with the diagonal, it forms a right triangle, making the diagonal the hypotenuse (c).
Diagonal: 62.48 inches
