In this rectangle, find m angle DEC. Please help me!!!!

notsponge [240]

Answer:

118°

Step-by-step explanation:

EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)

The total sum of angle EDC and ECD is 31 + 31 = 62°

The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.

180 - 62 = 118°

Part a:-
The base of each triangle is 4 inches long.
Their height is 3/2 * 4 = 6 inches.

The combined area of the triangular faces = 4 * 1/2 * 4 * 6 = 48 sq ins

c
Surface area of the pyramid = 48 + area of base = 48 + 16 = 64 sq ins.
