What are the steps to getting the value of x in 4(2x - 11) + 15 = 21 and explanation for each step?
tester [92]

4*(2x - 11) + 15 = 21

8x - 44 +15 = 21

8x = 21 + 44 - 15

8x = 50

x = 50 : 8

x = 6.25 or 25/4

If QS bisects PQT, SQT=(8x-25), PQT=(9x+34), and SQR = 112, find each measure
inna [77]

The value of

  • x = 12°
  • m∠PQS = 71°
  • m∠PQT = 142°
  • m∠TQR = 41°

Given

SQT = (8x₋25) and PQT = (9x₊34)

SQR = 112°

we need to find the x angle and the remaining angles.

we know that QS bisects ∠PQT

⇒ 2(8x₋25)° = (9x₊34)°

(16x ₋ 30)° =  (9x₊34)°

16x ₋ 9x = 34 ₋ 30

x = 12°

substitute x value in the given values of angles.

m∠PQS = (8x ₋ 25)° = (8(12)₋25) = 71°

m∠PQT = (9(12)₊34) = 142°°

m∠TQR = 112° ₋ ∠PQS = 112° ₋ 71° = 41°

hence we get the desired angles from the given angles.
