If 8x+6=4x+38
8x-4x=38-6
4x=32
x=32/4=8

Angle of A is equal to angle of B (mirrored)

Then angle of B is 4x+38 = 4*8+38 = 32+38=70

. If QS bisects angle PQR, m angle PQS = (7x - 6)° , and m angle SQR = (4x + 15)° , find m angle PQT. ​
Paul [167]

Answer:

94

Step-by-step explanation:

PQS = (7x - 6)°

SQR = (4x + 15)° since QS bisect PQR these two expressions must be equal

so

7x - 6 = 4x + 15 transfer like terms to the same side of the equation

7x - 4x = 15 + 6

3x = 21 divide both sides by 3

x = 7

also the sum of these two would give us the measure of PQR

7x + 4x + 15 - 6 = PQR

11x + 9 = PQR replace x with 7

11*7 + 9 = 86 this is the measure of angle PQR and also supplementary to PQT so the measure of PQT = 180 - 86

Factor completely x2 − 7x + 18
zubka84 [21]
<span>x2 − 7x + 18
is prime

there is no way you can make two numbers multiply to get positive 18 and add to get negative 7

</span><span>(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18</span>
