Question

Find the value of x.

Answer 1

Solution

a+148=180(Angles on a straight line equals180)

▪a=180-148=32

Now,

a+b=90(A right angle is equal to 90)

So,

▪b=90-a=90-32=58

Then,

b=b(base of iscoceles angles of traingle)

Now,

b+b+x=180(sum of angles of triangle equals 180)

or,58+58+x=180

or,x=180-116

▪x=64'
