Question

PQ ∥ RS. Find the value of a + b
if u don't no the answer then don't answer , I the answer is wrong the also don't answer.
please I need step by step answer
​

Answer 1

Step-by-step explanation:

Given that PQ||RS

✷Angle RPQ=Angle SRT {corresponding angles are equal}

•Angle SRT{Angle a}=45°

a=45°

➝Now let us take the triangle PQR

Angle RPQ+Angle PQR+Angle QRP=180°{sum of all angles in a triangle is 180°}

➝45°+55°+x°=180°

➝100°+x°=180°

➝x°=80°

➝Now let us consider the line PRS

Angle PRQ(x)+Angle QRT(angle b)+Angle TRS(angle a)=180{sum of all the angles on a straight line is 180°}

➝80°+Angle QRT+45°=180°

➝125°+Angle QRT=180°

➝Angle QRT=55°

b=55°

☞a+b

☞45°+55°

☞100°

✷The value of a+b=100°

Answer 2

Answer:

a = 45°.
