Question

find the value of x in each of the following.​

Answer 1

X is 50

Step-by-step explanation:

according to angle sum

40+90+x=180

130+X=180

X=180-130

X=50

Answer 2

Answer:

$i) 2x + x + 90 = 180 \\ = > 3x = 90 \\ = > x = \frac{90}{3} \\ = > x = 30$

$x + 40 + 90 = 180 \\ = > x = 180 - 130 \\ = > x =50$

$x + 69 + 49 = 180 \\ = > x = 180 - 118 \\ = > x = 162$
