One angle within a triangle is 76 degrees. What is the value of the exterior angle?
mrs_skeptik [129]

Answer:

The value of the exterior angle is 104\°

Step-by-step explanation:

we know that

The sum of the interior angle plus the exterior angle is equal to 180\°, because are supplementary angles.

Let

x-----> the measure of the exterior angle

so

76\°+x=180\°

solve for x

x=180\°-76\°=104\°

Eight less than 1/3 a number n is -13
Goryan [66]
1/3n - 8 = -13 <== ur equation
1/3n = -13 + 8
1/3n = - 5
n = -5 * 3
n = -15

check..
1/3(-15) - 8 = -13
-5 - 8 = -13
-13 = -13 (correct)

so the number (n) = -15
