I would like help ASAP please

Answer:

The measure of angle T is 135 degrees.

Step-by-step explanation:

Let's just say the measure of angles T and S are variables t and s.

So the equation would be...

t + s = 180

Since they are supplementary angles, they add up to 180.

Also, we know that t is 3 times s.

t = 3s

Now we can solve this system of equations.

Substitute 3s into t of the first equation.

3s + s = 180

4s = 180

s = 45

Then, since we know that the measure of angle t is 3 times the measure of angle s, we can just multiply 45 by 3 and find the measure of angle t.

45 * 3 = 135

t = 135

So the measure of angle t is 135.

What is Euclid's fifth postulate
Nataly [62]

Answer:

Euclid fifth postulate gives information regarding parallelism of lines.Euclid's fifth postulate states If a straight which falls on two straight lines makes interior angle on the same side of it.And if sum those two interior angles is less than 180° ,then two straight will not be parallel which means they if they produced indefinitely they will surely meet on the side where some of interior angles is less than 180°.

This postulate is more complex as compared to other four postulates.It says that two parallel lines never meet.This postulate is also known as parallel postulate.
