Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area (
):

The triangle's area (
):


Now add up all the sides. (3 Rectangles, 2 Triangles.)


The total surface area is 350.82 cm squared.
Answer:
Step-by-step explanation:
According to the ratios table, if
sin theta = 1/2
Then theta = 30°
Cos theta = cos 30° =root 3 /2
Step-by-step explanation:
okay
I think you should use the method of tan 30
and then find x by using pythagorean theorem
Answer:


Step-by-step explanation:
Given [Missing from the question]
Equation:

Interval:


Required
Determine the values of 
The given expression:

... shows that the value of
is positive
The cosine of an angle has positive values in the first and the fourth quadrants.
So, we have:

Take arccos of both sides

--- In the first quadrant
In the fourth quadrant, the value is:


So, the values of
in degrees are:

Convert to radians (Multiply both angles by
)
So, we have:
