Question

find the values of x and y

Answer 1

$Bonjuor!!$

✳ Let the given triangle be marked as A, B and C, such that,

Angle A = 70°
Angle B = x
Angle C = y

AND IT IS ALSO GIVEN THAT : AB = AC.
So, Angle B = Angle C.
Because, angles opposite to equal sides are equal.

✳ Now, as per "ANGLE SUM PROPERTY OF TRIANGLE",

✳ Angle A + Angle B + Angle C = 180°
◻ 70° + x ° +x° = 180°
◻ 70° + 2x° =180°
◻ 2x° = 180°-70°
◻ 2x° = 110°
◻ x° = 110/2
◻ x° = 55°

✳ As, Angle B = Angle C.
◻ Angle B = 55°
◻ Angle C = 55°

Answer 2

Hey mate here is your answer ⤵⤵⤵

From the figure,

AB=CD✔

angle x=angle y [angles opposite to equal sides of a triangle are equal]

Now ,

✔x+y+70°=180°

✔x+x=180°-70°

✔2x=110°

✔x=55°

=>x=y=$\bold {\color{red}{\boxed {55°}}}$✔
