Because there are more than 2 lengths for the sides and because the small triangle faces are right angles we will use this formula:
V=(1/2)bhl
which is equivalent to V=Al (A=(1/2)bh and A is Area)
b=12in
h=35in
l=40in
A=(1/2)•12in•35in
A=(1/2)•420in
A=210in^2
V=Al
V=(210in^2)•40in
V=8400in^3
Making your answer D. 8400 inches cubed
Hello!
Question 1
In a 30-60-90 triangle the hypotenuse is 2x the height is

and the base is x
Find x
11 = 2x
Divide both sides by 2
5.5 = x
Put in x into the other equations

x = 5.5
2x = 11
11 + 5.5 + 9.5 = 26
We put the equations into a calculator and see which one is close to 26
The answer is B) 33/2 + 11/2 * the square root of 3

Question 2
For this one we can put the choices into a calculator and see what comes up close to 15
tan(86.19°) = 15.01
the answer is D) 86.19°
Hope this helps!
Answer:
A 50
Step-by-step explanation:
According to the Inscribed Quadrilateral Theorem, opposite angles must be supplementary. With this, we can state that:
