Given that QT is an altitude of triangle QRS, measure of angle QTS=(6x+36), and QR = 2x – 5, find QR.
Alexeev081 [22]
We know that
if <span>QT is an altitude of triangle QRS
then
</span><span>the measure of angle QTS is equal to 90</span>°
so
6x+36=90-----> 6x=90-36----> x=54/6
x=9
QR=2x-5-----> QR=2*9-5-----> QR=18-5-----> QR=13

the answer is
QR=13

tanA=8/15 and tan B=40/9

tan(A+B)=(tanA+tanB)/1-tanAtanB

(8/15+40/9)/1-(8/15×40/9)

=-672/185
