Answer:
x = 9
Step-by-step explanation:
The big triangle is twice as big as the little triangle bc of the info given on midpoints.
So AC is twice as big as DE.
3x - 15 = 2(6)
3x - 15 = 12 ADD 15
3x = 27 DIVIDE BY 3
x = 9
Answer:
if you are solving for X
Step-by-step explanation:
first you do a thing i call jump multiplying
so like 5x2X+ 5x4
then you do basic maths
10X=20
X=2
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.
The answer is false. n^2 would become 6^2 which is equal to 36 not 12
