Question

in triangle abc angle b is equal to angle A + angle C upon 2 and Angle A ratio angle C is equal to 1 ratio 2 find the measure of each angle of a ABC​

Answer 1

Answer:

50°

Step-by-step explanation:

Check the figure, angle b and pqs are supplementary angles so b will be 180-100 = 80°

Similarly, angle c and angle prt will be supplementary,

so angle c will be 180- 130 = 50°

We know that a+b+c = 180°

so a will be 180-80-50 = 50°
