Find T. Is it 7 or -1

Mathematics
1 answer:
zvonat [6]3 years ago
6 0

Answer:

t = 5

Step-by-step explanation:

These 2 angles are supplementary which mean that together, they equal 180:

20t + 5 + 15t = 180

35t + 5 = 180

35t = 180 - 5

35t = 175

t = 175/35

t = 5

Find the value of z in the similar figures (round to the nearest tenth)
MrRa [10]
As they are similar figures,we can use the ratio of the side to find out the value of z.

The only side that both have the value indicated is 4 and 6,therefore we would use it to find the ratio.

The eqaution would be:
6/4 = z/8
3/2 = z/8
3×8 = 2z
z = 24/2
z = 12

Thus the value of z is 12.

Hope it helps!
