Right triangle FHG is shown. The sine of angle F is 0.53. What is the cosine of Angle h ?
g100num [7]

<u>Given</u>:

Given that FGH is a right triangle. The sine of angle F is 0.53.

We need to determine the cosine of angle H.

<u>Cosine of angle H:</u>

Given that the sine of angle F is 0.53

This can be written as,

sin F=0.53

Applying the trigonometric ratio, we have;

\frac{HG}{FH}=0.53 ----- (1)

Now, we shall determine the value of cosine of angle H.

Let us apply the trigonometric ratio cos \ \theta=\frac{adj}{hyp}, we get;

cos \ H=\frac{HG}{FH} ----- (2)

Substituting the value from equation (1) in equation (2), we get;

cos \ H=0.53

Thus, the cosine of angle H is 0.53

How would I solve for x?​
vaieri [72.5K]

Answer:

x = 65

Step-by-step explanation:

First, we calculate the unknown angle of the left triangle and right triangle:180 - 62 - 50 = 68

Unknown angle for left triangle⬆️

180 - 80 - 53 = 47

Unknown angle for right triangle⬆️

Now we've calculated the two angles for the small triangle in the middle. So, we just have to calculate the top angle of the middle triangle:

180 - 68 - 47 = 65

The angle 65° and angle of x are vertical angle.(both are equal)

So... <u>x= 65°</u>
