Answer:

Step-by-step explanation:
your are taking 4 and multiplying it by itself three times hence 4 to the third power
As QS bisects <RQT into 2 congruent triangles
therefore, <RQS = <SQT
4x-25= 2x+5
2x= 30
x= 15
<RQS = 4x-25
= 4(15) -25
=60-25
= 35
Answer:
x = 12
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
3x+19 + 5x = 115
Combine like terms
8x + 19 = 115
Subtract 19 from each side
8x+19 -19 = 115 -19
8x = 96
Divide each side by 8
8x/8 = 96/8
x =12
Should be 5/6 if you balance it by making the denominator the same
