The measures of the angles of a triangle are shown in the figure below. Solve
for x.
30°
(4x-4)

In this triangle it is given that one angle if of 30⁰ and another one is of 90⁰
so By using ANGLE SUM PROPERTY we can solve it
so,
30⁰+ 90⁰ + 4x - 4⁰ = 180⁰(ASP)
120⁰ + 4x - 4 = 180⁰
4x - 4 = 60⁰
4x = 64
x = 16⁰
Hence solved
hope it help u
