Answer:
m∠SRW =
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 =
<TRS = (2x + 18) = 92 x 18 + 18)
=
Also,
<TRV = <SRW (vertically opposite angles)
So that,
<TRU + <URV = <SRW
But,
<TRV + <SRW + <TRS + <VRW =
<TRV + <SRW +
+
=
<TRV + <SRW +
=
<TRV + <SRW =
-
<TRV + <SRW =
2 <SRW =
(∵ <TRV = <SRW)
<SRW =
=
Therefore,
m<SRW =
