Answer:
The value of x is 15°
Step-by-step explanation:
we know that
If in a right triangle (A and B are the acute angles)
sin(A)=cos(B)
then
angle A and angle B are complementary angles
so
A+B=90°
therefore
In this problem
sin(2x+14)°=cos(46°)
(2x+14)°+46°=90°
Solve for x
2x+60°=90°
2x=30°
x=15°
The value of acute angle x in the given right triangle is 15°.
As we know that
cosα = sin(90-α)......(1)
We can write the right-hand side of the given equation in sine form using equation (1)
What is an acute angle?
An acute angle is an angle that measures less than 90°
Given equation is
[tex]sin(2x+14) = cos 46\\\\sin(2x+14) = sin(90-46).....fromEQ1\\\\sin(2x+14) = sin 44\\\\2x+14 = 44\\\\2x = 30\\\\x = 15[/tex]
Therefore, the value of acute angle x in the given right triangle is 15°.
