3 lines are shown. A line with points T, R, W intersects a line with points S, R, W at point R. Another line extends from point R to point U between angle T, R, V. Angle V R W is (3 x) degrees and angle T R S is (2 x + 18) degrees.

What is m∠SRW?

18
54
126
108

Answer:

m∠SRW =
126^(o)

Explanation:

Given: <VRW = 3x

<TRS = (2x + 18)

What is m∠SRW?

<TRS = <VRW (vertically opposite angles)

2x + 18 = 3x

18 = 3x - 2x

x = 18

<VRW = 3x = 3 x 18 =
54^(o)

<TRS = (2x + 18) = 92 x 18 + 18)

=
54^(o)

Also,

<TRV = <SRW (vertically opposite angles)

So that,

<TRU + <URV = <SRW

But,

<TRV + <SRW + <TRS + <VRW =
360^(o)

<TRV + <SRW +
54^(o) +
54^(o) =
360^(o)

<TRV + <SRW +
108^(o) =
360^(o)

<TRV + <SRW =
360^(o) -
108^(o)

<TRV + <SRW =
252^(o)

2 <SRW =
252^(o) (∵ <TRV = <SRW)

<SRW =
(252)/(2)

=
126^(o)

Therefore,

m<SRW =
126^(o)
