Question

Find angle a and angle b. ​

Answer 1

Answer:

did I answer it wrong........,

Answer 2

Answer:

TU is parallel to SR.

TQ is transversal

then angle SRO=90.

angle SRT=90.

TR is parallel to SV.

angle TAS=90.(co. interior angles.)

then angle ASR=90.

angle PRQ=90.(linear pair)

In triangle PRQ

50+90+angle b=180

angle b= 180-140

=40

angleb is 40.

CONSTRUCTION:extend VU to X at SR.

angle RSV+ angle SVX=angle VXR(exterior angle property)

90+25=115.

angle VXR=115.

TAis parallel toSR

angle VXR =angle a.(corresponding angle)

then angle a is 115.
