Answer:
x = 5
Step-by-step explanation:
To break this down, I'll start from the first thing the question gives you. Triangle ACB is congruent to triangle DCE. This means that the angles and the sides of each triangle is the same. Now this next part is important. The way in which the letters are ordered is corresponds to what angles are the same. Since the triangles are congruent, ∠A in ΔACB would correspond to ∠D in DCE. Another example: ∠C in ACB is congruent to ∠C in ΔDCE. So if ∠A is congruent, or the same as ∠D, this means ∠D is 50°. Now, we just solve for x:
∠D = 10x
50° = 10x
Divide each side by 10 to isolate x:
50/10 = 10x/10
x = 5
Answer:
9
Step-by-step explanation:
The GCF between 54 and 27 is nine.
Answer:
5(2x+5)
Step-by-step explanation:
This is the answer because the highest multiple is 5 for both of them.
so since it is 5 divide both numbers by 5 put 5 outside the parenthisis and
then divide the numbers inside
this will give you - 5(2x+5)
Hope it helps :)
It’s gives x+5 I think I’m not sure
When you factor the equation...
r^2-4r-77
r^2+7r-11r-77
r(r+7)-11(r+7)
(r-11)(r+7) so each parenthetical term is a dimension.
Note that r>11 though for any possible real solution.
