Answer:
2.79
Step-by-step explanation:
Given
With reference angle 21°
hypotenuse (h) = 3
base (b) = x
Now
cos 21° = b / h
0.93 = x / 3
x = 0.93 * 3
x = 2.79
Hope it will help :)
Hey!
------------------------------------------------
x – 3y = 3 is written in standard form. We can write in the slope-intercept form.
x - 3y = 3
x - 3y - x = 3 - x
3y = 3 - x
3y/3 = 3/3 - 3/x
y = 1 - 3/x
y = 1/3x - 1
Now, we know that the y-intercept is -1 and the slope is 1/3
------------------------------------------------
Hence, the answer is

Hope This Helped! Good Luck!
Answer:
Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.
