Sin = opposite/hypotenuse
cos = adjacent/hypotenuse
They are the same when opposite equals adjecent.
This only occurs when the angles are equal.
Answer: 45°
Answer:
x=1/4
Step-by-step explanation:
you would take a away 1/2 from each side so it would look like this
x+1/2=3/4
<u>-1/2 -1/2</u>
x=3/4-1/2
and 3/4-1/2 is 3/4-2/4=1/4
x=1/4
Answer:
360 ≥ 8t
Step-by-step explanation:
Let t be the number of tables. Since there can't be more than 360 people, it has to be less than or equal to.
Answer:
1. After solving we get value of x: 
2. After solving we get value of x: 
Step-by-step explanation:
We need to Solve the equations.
1. 
Step 1: Subtract 5x on both sides

Step 2: Subtract 10 on both sides

Step 3: Divide both sides by -11

So, after solving we get value of x: 
2. 
Step 1: Subtract 5x on both sides

Step 2: Subtract 7 on both sides

Step 3: Divide both sides by -11

So, after solving we get value of x: 
Answer: hope this helps
Step-by-step explanation:
Simplifying
1.17 + -0.07a + (-3.92a) = 0
Combine like terms: -0.07a + (-3.92a) = -3.99a
1.17 + -3.99a = 0
Solving
1.17 + -3.99a = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-1.17' to each side of the equation.
1.17 + -1.17 + -3.99a = 0 + -1.17
Combine like terms: 1.17 + -1.17 = 0.00
0.00 + -3.99a = 0 + -1.17
-3.99a = 0 + -1.17
Combine like terms: 0 + -1.17 = -1.17
-3.99a = -1.17
Divide each side by '-3.99'.
a = 0.2932330827
Simplifying
a = 0.2932330827
