Step-by-step explanation:
2t + 8 <u>></u> - 4( t + 1)
2t + 8 <u>></u> - 4t - 4
2t + 4t <u><</u> - 4 +8
6t <u><</u> 4
Divide both sides by 6
T <u><</u> <u>4</u><u> </u>
6
t <u><</u> <u>2</u><u> </u>
3
I think that is the answer
Hope it helps :)

Answer:
Step-by-step explanation:
Angles x and z are supplementary, meaning that they add up to 180. From the markings on the diagram, angle z and the angle measuring 20 are complementary, meaning they add up to 90. So the game plan is to find out the measure of angle z first, then use that to find the measure of angle x.
angle z = 90 - 20 so
angle z = 70 degrees. And
angle z + angle x = 180. Subbing in our value for z:
70 + angle x = 180 and
angle x = 180 - 70 so
angle x = 110 degrees
