A list of angles is shown, where x° represents an unknown angle measure.
63°, 28°, x°
What is the measure of x, in degrees, for the three angles to form a triangle?



Answer :

Answer:

89 degrees

Step-by-step explanation:

as we know,

to for a triangle the sum of the angles should be 180 degrees

let a=63 b=28 so,

a+b+x=180

or, x=180-a-b

= 180-63-28

= 89
