Answer:
<u>m∠CAD is 100°</u>
Step-by-step explanation:
The angles of a triangle always add up to 180 degrees.
Add...
100+x=180
Subtract 100 from each side...
x=80°
m∠CAB=80
-------------
A line is always 180°... line DB consists of m∠CAB (just solved) and m∠CAD (which the answer asks)
m∠CAB+m∠CAD=DB
Substitute in the information we have.
80°+m∠CAD=180°
Subtract 80 from both sides...
<u>m∠CAD is 100°</u>
------------
I hope my answer makes sense to you! :)
Answer:
3 of the pyramids
Step-by-step explanation:
Given:
Hexagonal Prism
Hexagonal based pyramid
Required
How many of the pyramid will fill up the prism
To do this, we start by calculating the volumes of both shapes.
Let V1 be the volume of the hexagonal prism
Where: a = base and h = height
Let V2 be the volume of the hexagonal based pyramid
Where: a = base and h = height
The number of the pyramid that can occupy the prism is calculated by dividing V1 by V2
Convert division to multiplication
K = kims age, s = her sisters age
k = 2s
k + s = 36
2s + s = 36 <== ur equation
3s = 36
s = 36/3
s = 12 <== the sister is 12
k = 2s
k = 2(12)
k = 24 <== Kim is 24
