Answer: x=4
Step-by-step explanation:
similar triangle so corresponding parts are similar

cross multiply
70 = 20x-10
80 = 20x
x = 4
Answer:
177
Step-by-step explanation:
8.7×5×2=87
10×3×3=90
87+90=177
Answer:
the answer is 59
Step-by-step explanation:
Given that C is the midpoint of AB so from this result that AC = BC so given that AC = 20 => BC = 20 too
and given that AB = 5x so AB = AC +BC so AB = 20+20 so AB = 40
than AB = 40 and AB = 5x so result 5x = 40 => x = 40/5 so x = 8
