Question

Find the angle measure 'x' in the following figure

Answer 1

Answer:

X =140°

Step-by-step explanation:

From the figure it can be concluded that ,

70°+a=180°(linear pair)

a=110°

60°+b=180°(linead pair)

Sum of all interior angles of a pentagon is 540°.

120°+110°+30°+x+x=540°

260°+2x=540°

2x=540°-260°

2x=240°

x=240°/2

x=140°

Hope it helps^_^

Answer 2

Answer:

70+a=180 (Linear pair)

a=110

60+b=180 (Linear pair)

b=120

Sum of measures of all angles of pentagon =540

0

∴120+110+x+x+30=540

2x=280

x=140

0
