Answer:
h = 0.64 ft
Step-by-step explanation:
A = 14h
8.94427191 = 14h
h = 8.94/14
h = 0.638571429
h = 0.64 ft
Answer:
77 is 35% of: 220
Step-by-step explanation:
Answer:
i think A is the answer in sin and cos
Answer:
Step-by-step explanation:
∠1 and ∠2 are vertical angles.
∠1 = ∠2
<u>Part A:</u>
<u></u>
Create an equation and solve for x.
20x + 21 = 30x - 29
Add 29 and -20x on both sides.
20x + 21 + 29 - 20x = 30x - 29 + 29 - 20x
Simplify the equation.
50 = 10x
Divide both sides by 10.
=
Simplify the equation.
5 = x
Switch sides.
x = 5
<u>Part B:</u>
<u></u>
Let x = 5
20(5) + 21
Distribute.
100 + 21
Add.
= 121
Since both angles are vertical angles, they are equal.
∠1 = 121°
∠2 = 121°
Answer/Step-by-step explanation:
To solve the given expression, , the following steps as well as justification for each step is given below:
Step 1: state the given expression
(given)
Step 2: solve for x by subtracting 12.7 from each side of the equation.
Step 3: Apply the additive inverse rule and simplify (i.e the additive inverse of 12.7 is -12.7. when added, it gives us 0)
(additive inverse/simplification)
Step 4: additive identity rule (i.e. the 0 added to x = 0)
(identity property of addition)
