Find mㄥPQR if ray QT bisects ㄥPQR, mㄥRQT = (10x - 13)°, and mㄥPQT = (6x + 1)°.

Ivanshal [37]

It is given in the question that ray QT bisects ㄥPQR.

$m \angle RQT = (10x - 13), \ and \ m \angle PQT = (6x + 1)$

And we have to find the measurement of angle PQR.

Since QT bisects angle PQR, therefore measurement of angle RQT and angle PQT are equal. That is

$10x-13=6x+1
\\
4x =14
\\
x = 3.5$

Substituting the value of x, we will get

$m \angle RQT=10*3.5-13 = 22 degree$

And measurement of angle PQR is twice of the measurement of angle RQT, that is

$m \angle PQR= 44$

Answer:

The answer is 10 I believe! A whole triangle is equal to 180 degrees so 180-70-60-60= -10. So we have to add 10 to equal it to zero. Hope this helped
