For this equation, you'll need to set x to 0 and solve from there.
First step is to solve the parentheses and then square the answer. Your equation will look like this:
Next, you will multiply -16 and 1, and then add the product of that by 21. Your answer will be
In short, the ball is thrown from 5 feet above ground.
The model ship would be 24 feet long. You just divide 888 by 37.
Answer:
Exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
Step-by-step explanation:
Given:
Cos(45° - 60°)
We have to apply the formula of cosine for difference of the two angles.
Formula:
Plugging the values.
⇒
We know that the values :
and
So,
⇒
⇒
⇒
⇒ ...<em>rationalizing </em>

⇒ ...<em>taking 2 as a common factor</em>
<em>⇒ </em>
To find the exact values we have to put the values of sq-rt .
As<em>, </em> and
Then

<em>⇒ </em><em />
⇒
So the exact value of Cos(45° - 60°) is 0.96 using difference of two angles.
Answer:
35
Step-by-step explanation:
hope it helps :)
We know that
if sin (x + 22°<span>)=cos (2x - 7</span>°<span>)
then
</span>(x + 22°) and (2x - 7°)------> are complementary angles
so
(x + 22°) +(2x - 7°)=90-------> 3x+15=90------> 3x=75------> x=25°
the answer is
x=25°
