Question

Please give step by step explanation of both parts​

Answer 1

Answer:

1) 40+ x = 110 ( sum of two interior angles equals to sum of two interior opposite angles)

= x=110-40

x= 70

(2) Give triangle is an right angle triangle =90°

x=?

= 25+x= 180

x= 180-25

155

Step-by-step explanation:

hope it will help u....

Answer 2

i. x+40 = 110° ( exterior angle property)

x = 110-40

x = 70

ii. x+25+90 = 180° (angle sum property)

x+115 = 180

x = 180-115

x = 65°
