So triangles bcd and aec are similar. so this makes lines ac and bc similar and lines db and ae similar.
to solve this problem, we just need to do some algebra

now we substitute those values in

which results in

then multiply both sides by 12

soon you should get x=2 with the length of ae being 16
Answer: 56in³
Step-by-step explanation:
Let the volume of solid B de denoted as x. Based on the information given in the question, we can solve further by:
1/2 = 28/x
Cross multiply
1 × x = 2 × 28
x = 56
Therefore, the volume of solid is 56in³.
Find the value of θ,
θ = arccos -8/9 = 152.734 deg
You can substitute this value for the requirement.
tan 152.734 = -0.51539
sin 152.734 = 0.45812
Which question are you talking about 1 or 2?
The base must be perpendicular to the height for area= bh/2.
We can use RS as the base and TU as the height.
6*3/2
18/2
9
Final answer: 9 units^2
