Question

In the given figure, l =11m find angle x


pls give the answer correctly​

Answer 1

it is sum is 180

`x + 130 + 140 = 180 \\ x + 270 = 180 \\ x = 180 - 270 \\ x = - 60`

Answer 2

Solution given:

CL || AM

<BCL=130°

<BAM=140°

<ABC=?

Construction:

BN || CL is made:

let

now

< BCL+<CBN=180°[shows a. property of co interior angle]

130°+p=180°

subtracting both side by 130°

130°-130°+p=180°-130°

p=50°

again

<BAM +<ABN=180°[shows property of co interior angle]

140°+q=180°

subtracting both side by 140°

140°-140°+q=180°-140°

q=40°

we have

<ABC=x=<ABN+<CBN=q+p=40°+50°=90°

Therefore the angle x=90°
