Answer:

a = 57.5

b = 57.5

Explanation:

XY=XZ so c=d


c = d = (180 - 65)/(2) = 57.5

Now draw the XH

So angle YXH = 180 — 90 — 57.5 = 32.5

a+YXH=90

a+32.5=90

so a = 57.5

We know that a + 65 + b = 180

So 57.5 + 65 + b = 180

b = 180 — 122.5

b = 57.5

From the above diagram we can conclude that ~

Angle c = Angle a (Alternate interior Angle pair)

Angle d = Angle b (Alternate interior Angle pair)

and,

  • Angle c = Angle d

because their opposite sides are equal.

now, according to linear pair property ~

  • Angle a + Angle b + 65° = 180°

replacing Angle a with Angle c and Angle d with Angle b, because they are equal to one another ~

  • Angle c + Angle d + 65° = 180°

  • 2 × Angle c = 180° - 65°

(because Angle c = Angle d)

  • 2 × Angle c = 115°

  • Angle c = 115° ÷ 2

  • Angle c = 57.5° = Angle d

So,

  • Angle a = Angle c = 57.5°

  • Angle b = Angle d = 57.5°
