2. An exterior ange of a triangle measures 140% and its interior opposite anger
3:4. Find the angles of the triangle​

Answer 1

Answer:

the angles of triangle are 60°, 80° & 40°

Step-by-step explanation:

exterior angle=sum of remote interior angles

:.lets take multiple x

:.140°=3x+4x

140=7x

x=140/7

x=20

3x=3*20=60°

4x=4*20=80°

lets take the left angle y

:.60+80+y=180° -- sum of measure of angles of triangles is 180

140+y=180

y=180-140

y=40°
