Question

the angle of a triangle are in AP if the smallest angle is 50 find the other two angle
​

Answer 1

Answer:

$\huge\mathbb\blue{♡Answer♡}$

Explanation:

$\large\star{}$a = 50 (smaller angle)

a2 = 50 + d (second A P)

a3 = 50 + 2d

sum of Angles of triangle= 180

50 + 50 + d + 50 + 2d = 180

150 + 3 d = 180

3d = 180 - 150

3d = 30

d = $\frac{30}{3}$

d = 10

so, the second AP or second angle = 50 + d

= 50 + 10

= 60

third angle = $= 50 + 2d \\ = 50 + 20 \\ = 70$

angle s are 50°,60°,70°

Answer 2

Answer:

⋆ a = 50 (smaller angle)

a2 = 50 + d (second A P)

a3 = 50 + 2d

sum of Angles of triangle= 180

50 + 50 + d + 50 + 2d = 180

150 + 3 d = 180

3d = 180 - 150

3d = 30

d =

3

30

d = 10

so, the second AP or second angle = 50 + d

= 50 + 10

= 60

third angle =

=50+2d

=50+20

=70

angle s are 50°,60°,70°
