10. Given ADEF, if DE = 50 inches and EF = 19 inches, what is m2D to the nearest tenth
of a degree?
A. 16.1*
B, 18.5
C. 20.7°
D. 22.3
Hel

yes

step-by-step explanation:

the answer is a.

135 and 80

step-by-step explanation:

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
