Question

please find out the solution​

Answer 1

Step-by-step explanation:

y = 180⁰ - 140⁰ [as QRS is straight angle.]

= 40⁰

x = 180⁰- (60⁰+40⁰) = 180⁰ - 100⁰ = 80⁰. [ Sum of angles of triangle is 180⁰].

or,

60⁰+x = 140⁰ [ sum of two interior angles away= the exterior angle.]

x = 80⁰.

Answer 2

Answer:

by the following diagram value of x and y is

Step-by-step explanation:

first we has to find the value of y

we know that straight line means 180° it means y+140°=180°

y=180°-140°

y= 40°

now we has to find the value of x

sum of interior angles of a triangle =180°

it means x+y+60°= 180°

we already x value equal to 40°

60°+40°+y= 180°

100°+y=180°

y=180°-100°

y=80°

now we got x and y values as 40° and 80°
