Question

Sum and difference of two angle of a triangle are 128 degrees and 22 degrees respectively then the third angle is

Answer 1

Answer:

third angle = 52 degrees

i hope this answer will help you

Step-by-step explanation:

a + b = 128

a - b = 22

________

2a = 150

a = 75, b = 128 - 75 = 53

sum of all angles in a triangle is 180 degrees.

therefore, a+b+c = 180

75+53+c = 180

c = 180-75-53 = 52

Answer 2

a+b =128
a-b= 22, a = 22+ b
22+b +b = 128
2b = 128-22, b = 106/2 , b= 53 , a = 75
a+b+c = 180
c = 180-128= 52
third angle = 52
