Which correctly describes how to determine the measure of angle 1? the 81° angle and angle 2 are corresponding angles so angle 2 must measure 81°. angles 1 and 2 are supplementary angles so angle 1 must measure 99°. the 81° angle and angle 2 are alternate interior angles so angle 2 must measure 81°. angles 1 and 2 are supplementary angles so angle 1 must measure 99°. the 81° angle and angle 2 are corresponding angles so angle 2 must measure 99°. angles 1 and 2 are supplementary angles so angle 1 must measure 81°. the 81° angle and angle 2 are alternate interior angles so angle 2 must measure 99°. angles 1 and 2 are supplementary angles so angle 1 must measure 81°.

The first one is correct.

The 81° angle and angle 2 are corresponding angles so angle 2 must measure 81°. Angles 1 and 2 are supplementary angles so angle 1 must measure 99°.

Let's go through the rest of them.

The 81° angle and angle 2 are alternate interior angles so angle 2 must measure 81°. Angles 1 and 2 are supplementary angles so angle 1 must measure 99°.

2 isn't an interior angle.

The 81° angle and angle 2 are corresponding angles so angle 2 must measure 99°. Angles 1 and 2 are supplementary angles so angle 1 must measure 81°.

Corresponding angles are congruent, with the same measure.

The 81° angle and angle 2 are alternate interior angles so angle 2 must measure 99°. Angles 1 and 2 are supplementary angles so angle 1 must measure 81°.

81 and angle 2 aren't alternate interior and if they were they'd be congruent.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315
