Question

Angle JKL is a straight angle.

The measure of angle MKL is 140
is
.
The measure of angle JKM is x

.What is the value of x
?

Answer 1

Answer: x = 40°

Step-by-step explanation:

∠jkl is a straight line then it is equal to 180°

now ∠mkl + ∠jkm = ∠jkl = 180°

∠mkl = 140°  

140° + x = 180°

x = 180 - 140

x = 40°

Answer 2

Given,

∠JKL is straight angle.

∠MKL = 140° and ∠JKM  = x

We have to find the value of x is:

Solution:

We know that,

Straight angle, ∠JKL = 180°

∴ ∠MKL + ∠JKM = ∠JKL

⇒ 140° + x = 180°

⇒ x = 180°  - 140°

⇒ x = 40°

∴  x = 40°

Thus, the value of "x is equal to 40°" .
