Question

x,y and z are three angles lying on a straight line.
(a)if y =45 and z=86, find the value of x.
(b)if x=2y and z= 3y,find the value of y.​

Answer 1

Answer:

a) 49

Step-by-step explanation:

a) bcoz of straight line x+y+z=180

45+86+x=180

x=49

Answer 2

a) The value of x is 49 degrees.

b) The value of y is 30 degrees.

Step-by-step explanation:

We are given the following in the question:

x, y and z are three angles lying on a straight line.

Thus, the sum of measure of the three angle is 180 degrees.

a)  y = 45 and z = 86

$x + y + z = 180\\x + 45 + 86 = 180\\x = 180 - (45 + 86)\\x = 49^\circ$

b)  x = 2y and z = 3y

$x + y + z = 180\\2y + y + 3y = 180\\6y = 180\\y = 30^\circ$
