Question

in the following figures, PQ||RT. find the values of: (i) a and b. (ii) a+b​

Answer 1

Answer:

where is the figure?

attach the image of figure!

please follow

Answer 2

applying angle sum property in triangle PQR,

∠PRQ+∠RQP+∠QPR = 180 degree

∠PRQ+45   degree +55  degree =180  degree

∠PRQ = 80  degree

∠PRQ+∠QRT+∠TRS = 180  degree   (angles forming a straight line)

80  degree +a+b = 180  degree

a+b= 100  degree

Have A Great Day !!
