Question

find the measure of X in each of the following​

Answer 1

Step-by-step explanation:

Mark 1 angle y= 60+70+y=180

y=180-130=50

Now x,

50+40+2x=360

2x=360-90

x= 270/2= 135

Answer 2

Answer:

X = 135

Step-by-step explanation:

The angle between 60⁰ and 70⁰ = 50

(as it was a straight line it forms 180⁰ so sum of all angles = 180⁰)

X + X + 40 + 50 = 360 ( sum of all the angles of a quadrilateral is 360⁰)

2x + 40 + 50 = 360

2x + 40 = 360 - 50

2x + 40 = 310

2x = 310 - 40

2x = 270

X = 270/2

Therefore.

X = 135⁰

2x = 310 - 40

2x =
