The value of angle x is approx 49⁰.
How the measure of x is calculated.
Trigonometric ratios are ratios of the sides in a right-angled triangle, including sine, cosine, and tangent etc.
From the figure, the given triangle is a right angle triangle
Let us use trigonometric ratios
tan x = opposite/adjacent
Opposite to the angle x = 7.7 cm
The adjacent = 8.9 cm
tan(x) = 8.9/7.7
tan(x) = 1.1558
x = tan⁻¹(1.1558)
x = 49.13⁰
approx 49⁰
The value of angle x is approx 49⁰
