4. Solve for t:
-4t - 4) = 20
a) t = 9
b) t = -9
c) t= 1
d) +=-1

Can you solve for t?

t=-6

Step-by-step explanation:

-4t-4=20 (move constant to the right)

-4t=20+4 (Calculate 20 + 4)

-4t= 24 (then divide 24 on both sides)

2,160 π

step-by-step explanation:

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
