Hello we know that the triangles are proportional so they have the same ratio
the unknown side is 21 because of this.
18/6=3/1
for each 1 unit in the bottom triangle there are 3 in the top
9×3=21
D+ 20= total

If a=0, then the denominator is equal to 0. Since you cannot divide by zero, you are not allowed to do this.
Answer:
x^10
Step-by-step explanation:
x^10
Answer:
8
Step-by-step explanation:
66 ÷ a = a + 2, anything that has R2 can also be rewritten to be plus 2. Then if you move 2 to the other side it becomes, (66 ÷ a) - 2 = a. Moving a to the other side will create this equation 66 - 2 = a x a. Therefore, 64 = a ^ 2. You just have to find the square root of 64 then.
