Question

The angles of a triangle are (10x-5)°,(15x - 10)° and (25x - 5)°
. Find their degree measure.​

Answer 1

Answer:

35°,50°,95°

Step-by-step explanation:

10x-5+15x-10+25x-5=180°

50x-20=180°

50x=200°

x=4°

Angle 1 - 10×4-5

=35°

Angle 2 - 15×4-10

=50°

Angle 3 - 25×4-5

=95°

Answer 2

Answer:

The sum of angles of triangle is 180°

(10x-5)+(15x-10)+ (25x-5)= 180°

50x-20 =180°

50x=200°

x= 4°

for, first angle (10x-5)= 10×4-5= 40-5 =35°

second angle (15x-10)= 15×4-10= 60-10 =50°

third angle ( 25x-5)= 25×4-5 = 100-5 = 95°
