Question

if the measure of one angle of right angles triangle is 48 degree find the other two angles

Answer 1

as right angle triangle has one angle is 90 degrees.
the first angle is given as 48
the second Angle is 90
the third angle is 42. (90-48)

second method
let the third angle be X
one of the angle in right angle triangle is always 90.
we know that sum of three angles of triangle=180°
therefore....90+48+X= 180
138+X= 180
X= 180-138.
X=42°
