pls help and write the steps as well ​

Answer 1

Answer:

Step-by-step explanation:

First let's find x :-

Total sum of a triangle = 180 degrees

Given angles = 55 + 60 + x = 180

= 180 - ( 55 + 60) = x

= 180 - 115 = 65 degrees = angle x

now let's find angle y :-

Angle x and the opposite angle makes 180

angle x + opposite angle = 180

= 180 - 65 = 115

now,

115 + 40 + y = 180

180 - ( 40 + 115 )

180 - 155 = 25 degrees

so, angle y = 25 degrees

Answer 2

Answer:

x=65°      y=25°

Step-by-step explanation:

x

when u add all the angles in a triangle they add up to 180°

60°+55°+x= 180°

115°+x=180°

115°-115°+x=180°-115°

x=65°

y

we need to find that missing angle opposite 40°, it will be renamed t to ease the solving of y.

so x+t=180°

65°+t=180°

65°-65°+t=180°-65°

t=115°

y

40°+115°+y=180°

155°+y=180°

155°-155°+y=180°-155°

y=25°
