Isaac determined the measure of each of the four angles in a quadrilateral. the measures of the angles are listed below.

• 62°
• 81°
• 82°
• 132°

isaac claimed that the measures of the angles in the quadrilateral were incorrect. which of the following statements best explains why isaac’s claim is accurate?

the sum of the measures of the angles in a quadrilateral must add up to 180°.

the sum of the measures of the angles in a quadrilateral must add up to 360°.

the sum of the measures of the angles in a quadrilateral must add up to 540°.

the sum of the measures of the angles in a quadrilateral must add up to 720°.

sine

step-by-step explanation:

so the possibilities of the measurement of the side of the triangle are either it is longest side or not the longest side

when it is the longest side

s < 25 + 35s < 60

if it is not the longest side

35 < 25 + s10 < sso 10 < s < 60so the perimeter70 < p < 130

your answer is

a.

5

step-by-step explanation:

part a: triangles gcb and epb

part b. sides cg and rp are parallel by definition of parallelogram.

angles cgb and e are congruent by being alternate interior angles of parallel lines cut by a transversal. angles gbc and ebp are congruent because they are vertical angles. by aa similarity, the triangles are similar.

part c. since the triangles are similar, the ratios of the lengths of corresponding sides are equal.

calculation of be:

gb/be = cb/bp

(400 ft)/be = 300/200

(400 ft)/be = 3/2

3be = 2 * 400 ft

3be = 800 ft

be = 800/3 ft

calculation of pe:

gc/pe = cb/bp

(350 ft)/pe = 300/200

(350 ft)/pe = 3/2

3pe = 2 * 350 ft

3pe = 700 ft

pe = 700/3 ft
