D.) 119º

Step-by-step explanation:

All angles in a triangle have to add up to 180º. Add 87º and 32º to get 119º, then subtract from 180º to get 61º. Angle C is 61º. Since it's also supplementary to 1, subtract 61º from 180º. 1 is 119º.

D) 119°

C) The two angles are supplementary.

Step-by-step explanation:

First problem:

<1 is an exterior angle of the triangle.

<A and <B are interior angles of the triangle far from <1.

For <1, angles A and B are called remote interior angles.

Theorem:

The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles.

m<1 = m<A + m<B

m<1 = 87° + 32°

m<1 = 119°

D) 119°

Second problem:

AB is a line. The diagonal line intersects line AB forming 4 angles, a, b, c, and d. Angles c and d are next to each other, called adjacent angles, and have a common side, and the other two sides lie on line AB. That makes angles c and d a "linear pair."  Two angles in a linear pair have measures that add to 180°, so angles c and d are supplementary angles.

C) The two angles are supplementary.

~courtney

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

x=17

answer:

x=17
