From right triangle trigonometry, we have the following:

,
where the "opposite side" means the opposite side to angle with measure

, and "adjacent side" means the adjacent side to angle with measure

.

is a constant which can be found using a calculator.
In the calculator of the pc press: view - scientific - 35 - tan.
This gives

Thus, back in the equation

we substitute as follows and solve:


Answer: 8.4 cm
A
Working:
Tan(angle)=opposite/adjacent
Tan60 = x/7root3
x=7root3 x Tan60
Enter in calculator
x=21
Make an equation.
'is' is an equal sign
The blank can be 'x'
'of' = multiplication
18 = x * 30
Multiply:
18 = 30x
Divide 30 to both sides:
x = 0.6
Multiply by 100:
0.6 * 100 = 60%
Answer:
g=
4x−7
x
Step-by-step explanation:
Answer:
12x = 84
x = 7
Step-by-step explanation:
12x = 83 1/3 + 2/3
12x = 84
x = 84/12
x = 7
Hope that helps!
