Answer:
x=21.4
Step-by-step explanation:
As we know the values of:
Perpendicular=10
Angle=25 degrees
And
Base=x
As the triangle is a right angled triangle, we will use the trigonometric ratios to find the value of x. As we have to find base and we know the values of perpendicular and angle, we will use a ratio that will include base and perpendicular.
So,
tan x=Perpendicular/Base
tan 25=10/x
x=10/tan 25
x=10/0.4663
x=21.4454
Rounding off to the nearest tenth
x=21.4
