Ответ:
The correct answer is option(b). 44°
Step-by-step explanation:
From the figure we can see a right angled triangle with one angle is x° and two sides are given.
To find the value of x
From the given figure we get the adjacent side of angle is given
Therefore we can write,
Cos x = Adjacent side/Hypotenuse
= 15/21
= 0.7142
x = Cos ⁻¹ (0.7142)
= 44°
Therefore the value of x = 44°
The correct answer is option(b). 44°
