Two angles are supplementary. One angle is 25°. What is the measure of the other angle?

The other angle is 155°.

Step-by-step explanation:

Supplementary angles are two angles that have a sum of 180°.

I found my answer my subtracting 25 from 180 (180-25) and my difference was 155.

And, 155 + 25 = 180°.

Therefore, the other angle is 155°.

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the answer is 40.
