slant height(h) = 16.3ft
Base side = 20ft

Perimeter of base = 4(base side) = 4(20) = 80ft
Answer:
Use the Triangle Sum Theorem (all three angles inside a triangle add up to 180 degrees)
A is 27, C is 90 degrees (right angle) , B is unknown.
Now add. 117+B=180
B is 63 degrees.
D is 31 degrees, E is 90 degrees. F is unknown.
Add.
31+90+F=180
121+F=180
F is 59.
Step-by-step explanation:
Solution:
Upper Quartile = 17
Lower Quartile = 14
Interquartile range = 17 - 14
= 3
The answer is 2:11 because yes that’s the ratio
17 bc it's in the middle (btw I didn't make that up my teacher in 6th grade said that)
