Answer:
<EFD= 47.5°
<CFD=47.5°
Step-by-step explanation:
Seeing that 85° is already there and it would be an opposite angle to <BFC all you would have to do is subtract that 85° from 180° because that's the angle of a straight line. then when you get 95° you divide it by 2.

3x + 10 = 5x + 22
Reorder the terms:
10 + 3x = 5x + 22
Reorder the terms:
10 + 3x = 22 + 5x
Solving
10 + 3x = 22 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
10 + 3x + -5x = 22 + 5x + -5x
Combine like terms: 3x + -5x = -2x
10 + -2x = 22 + 5x + -5x
Combine like terms: 5x + -5x = 0
10 + -2x = 22 + 0
10 + -2x = 22
Add '-10' to each side of the equation.
10 + -10 + -2x = 22 + -10
Combine like terms: 10 + -10 = 0
0 + -2x = 22 + -10
-2x = 22 + -10
Combine like terms: 22 + -10 = 12
-2x = 12
Divide each side by '-2'.
x = -6
Simplifying
x = -6</span>
Area of a triangle = 1/2 x base x height
= 1/2 x 6 x 7 = 3 x 7 = 21 square units.
