What is the measure of zadc in quadrilateral abcd?
o 45°
o 65°
o 115°
o 135

The measure of angle ADC is 115°

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The quadrilateral ABCD is a isosceles trapezoid.

The properties of the isosceles trapezoid are as follows:

-The lower base angles are congruent.

-The upper base angles are congruent.

-Any lower base angle is supplementary to any upper base angle

So

m∠A=m∠D

m∠B=m∠C

m∠A+m∠B=180°

m∠D+m∠C=180°

therefore

m∠D=m∠A=115°

m∠B=180°-m∠A

m∠B=180°-115°

m∠B=65°

m∠C=m∠B=65°

The measure of angle ADC is 115°

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
