Question

In triangleXYZ, angleX=3, angleY and angleZ=2 angleY, then the measure of angleX=? (Pls help me ;-;)

Answer 1

Answer:

90 degrees

Step-by-step explanation:

Angel X+Angle Y+Angle Z=180 deg.

Put the values of Angle X And Z in their respective positions and leave angle Y as it is.

So,3 Angle Y+Angle Y+2Angle Y=180 deg

6 Angle Y=180

Hence, Angle Y=30 deg.

And Angle X=3 Angle Y=3×30=90 deg.
