Step-by-step explanation:
Answer:
x=2
Step-by-step explanation:
3x+17=14x-5 so...
22=11x (subtract 3x and add 5 to both sides)
2=x (divide both sides by 11)
Answer:
x=2,-8
Step-by-step explanation:
<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,

Applying the trigonometric ratio, we have;
----- (1)
Now, we shall determine the value of cosine of angle H.
Let us apply the trigonometric ratio
, we get;
----- (2)
Substituting the value from equation (1) in equation (2), we get;

Thus, the cosine of angle H is 0.53
