In △abc , m∠a=72° , m∠b=(8y−16)° , and m∠c=(9x)° . isosceles triangle abc. ab is the base, lateral sides ac and cb are marked congruent. what are x and y?

ΔABC = isosceles => ∡B = ∡C

∡B = ∡C = (180°-72°) : 2 = 108° : 2 = 54°

∡B = 54° = 8Y - 16

54 + 16 = 8Y

70 = 8Y

Y = 8.75°

∡C = 54° = 9X

X = 54 : 9

X = 6°

step-by-step explanation:

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !
