We need the figure to answer that.
Answer:
D
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180
x = 180° - (90 + 35)° = 180° - 125° = 55°
----------------------------------------------------------
Since the triangle is right use the cosine ratio to solve for b
cos35° =
= 
Multiply both sides by 20
20 × cos35° = b, hence
b = 16.38 ( to 2 dec. places )
right angles or 90º angles
Answer:
Alternate Exterior Angles
This is easy. You basically round them all up. So 1.8 would turn into 2, 2.9 would turn into 3, and 5.7 would turn into 6. So now you have 2, 3, and 6. Now to calculate volume, you multiply length time width times height. So you multiply 2x3x6, and your answer is
36ft³
