Plzz solve this don't samp​

Answer 1

Answer:

i.)70°

ii.)60°

iii.)40°

(Sum of all the angles of the ∆ is 180°)

Answer 2

Answer: a) 70 degrees b) 40 (degrees) c) 40( degrees)

Step-by-step explanation:

1) 50 + 60 +x = 180

= 110 +x = 180

=  x = 180 - 110

x = 70 (degrees)

2)  

 where pqr  is a right angled trianlge

p = 90 degress

90 + 30 + x = 180

120 + x = 180

x  = 180 - 120

x = 40 (degress)

3)

30 + 110 + x = 180

140 +x = 180

x = 180 - 140

x = 40 (degress)
