Answer:
The value of x = 1
Step-by-step explanation:
Given
To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 45°
adjacent of 45° = x
hypotenuse = √2
so substituting Ф = 45° adjacent = x and hypotenuse = √2 in the equation
cos Ф = adjacent / hypotenuse
switch sides
Multiply both sides by 2
∵
Divide both sides by √2
Therefore, the value of x = 1
Answer:
135 square feet.
Step-by-step explanation:
A triangular prism. The rectangular sides are 8 feet by 2.5 feet, 8 feet by 6 feet, and 8 feet by 6.5 feet. The triangular sides have a base of 2.5 feet and a height of 6 feet.
The prism has two triangular faces and three rectangular faces.
So, the surface area of the prism will be
= 15 + 20 + 48 + 52
= 135 square feet. (Answer)
