Question

In an isosceles right angled triangle XYZ, angle Y = 90 degree.What is the measure of angle X?​

Answer 1

Answer:

45

Step-by-step explanation:

in an isosceles right angle triangle, one angle is 90° as the name indicates. other two angles are same.. In a triangle, sum of internal angle =180°

< x+<Y+<z=180

given <Y=90°

<X+<Z=180-90=90

<X=<Z(in an isosceles triangle, two angles are equal)

therefore, <X=<Z=90/2=45

so <X=45°

Answer 2

Answer:

X=45 degrees.

Step-by-step explanation:

In an isosceles triangle two angles are found to be equal, so

Y= 90 degrees

Let X and Z be angle x,

By Angle Sum Property

X+Y+Z= 180 degrees

or, x+90+x=180

or, 2x=180-90

or, x=90/2

or, x=45

Therefore, angle X is equal to 45 degrees.
