Question

in an isosceles ∆xyz,x and y are equal if z is equal to 36°,find the measure of x and y​

Answer 1

Answer:

Measures of angle x and y is 72°

Step-by-step explanation:

Given

Angle x and angle y are equale.

And measure of angle z is 36°

Let the angle x and y be a°

Then,

According to the question

Sum of angles of triangle = 180°

angle x + angle y + angle z = 180°

a + a + 36° = 180°

a + a = 180° - 36°

2a = 144°

a = 144°/2

a = 72°

angle x = a = 72°

angle y = a = 72°

ISOSCELES TRIANGLES

• Isosceles triangle is a triangle in which measures of two angles of triangle is equal.
• Then, two sides of this triangle is always equal.
• Sum of angles of triangle is 180°.
