Question

In the following figure, find the angles a, b and c.

Answer 1

Step-by-step explanation:

50°+25°+a=180°

a=180°-75°

a=105°

50°+b=180°

b=180°-50°

b=130°

a+25°+c=180°(a=105°)

105°+25°+c=180°

c=180°-130°=50°

c=50°

Answer 2

Answer:

angle a = 105°

angle b = 130°

angle c = 50°

Step-by-step explanation:

the sum of all the angles of the given figure will be 360°

the angle of a straight angle is 180°

to find angle a

given 50° and 25° so add the angle and subtract it from 180° to get a so the a will be

180°-50°+25°=125°

to find angle b

angle b+angle c will be 180°

b+50°=180°

b=180°-50°

b=130°

to find angle c

the adjacant angles are always same

angle c is adjacant to angle measuring 50° son angle c will be 50°
