Answer:
The length of x in the simplest radical form with a rational denominator will be:
Step-by-step explanation:
Given
hypotenuse = 5
angle Ф = 60°
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 60°
adjacent of 60° = x
hypotenuse = 5
so substituting Ф = 60°, adjacent = x and hypotenuse = 5 in the equation
cos Ф = adjacent / hypotenuse
so


switch sides

Multiply both sides by 5

Simplify

Therefore, the length of x in the simplest radical form with a rational denominator will be:
Answer:
5 units
Step-by-step explanation:
Area of triangle = 1/2 × base × height
30 = 1/2 × 12 × height
Height = 30 × 2/12 = 5 units
Answer:
i think its 22
Step-by-step explanation:
perimeter is all sides added together. so i just added the units
Answer: - (4 1/4)
Solution:
(6 1/2 + 2 3/4) - 1.5*(4.5/0.5)=
(6 0.5 + 2 0.75) - 1.5*(9)=
(6.5+2.75) - 13.5=
(9.25) - 13.5=
- 4.25=
-(4 0.25)=
-(4 1/4)
