Answer 1

Answer:

a) a= 18,b=144

b) c=53 , d=127

c) first one is isosceles triangle(two are equal )

second one is equatorial triangle(all sides are equal)

third one is not a triangle( there is no one side)

Step-by-step explanation:

a) a and 162° angles are on sane straight line so there sum is equal to 180°

a+162=180

a=18

we know that sum of two interior angles is equal to one exterior angle so

a+b=162

b=162-18=144

b) if we see the figure 53°and c are alternate angles so they are equal so c=53

if we see c and d are on same straight line so

c+d=180

d=180-53=127
