The arc shown is 140 degrees. Find the measure of angle 1.

1 answer:

3 0

The angle subtended by two chords is half the enclosed arc measure. If we imagine one of the chords getting shorter and shorter this remains true. In the limit the shrinking chord becomes a tangent, and the angle is still half the arc measure.

Answer: 70 degrees

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
