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.

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

it alot will look like this 4.4

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
