Answer:
the answer is b
Step-by-step explanation:
i took the test it is b. The sum of the areas of faces A, B, and C.
11154/52= 214 1/2 is the answer to this question
Triangle ABE is isosceles / Given
AB congruent to AE / Def isosceles
angle ABE congruent to angle AEB / Property of isosceles triangles
angle ABD congruent to angle AEC / Subst different name for same angles
BD congruent to EC / Given
triange ABD congruent to triange AEC / Side Angle Side
The answer is 10 because all the angles are equal making it a equilateral triangle.
Therefore, the sides are all equal to one another, 3x - 8 = 5x - 20.
You just solve for x and get 6. You then plug in 6 for x and evauluate the equation, getting 10.
set up an equation to solve for x
2-x ≥ 0
subtract 2 from each side:
-x≥ -2
multiply both sides by -1 ( to make x positive) and reverse the sign
x≤2
