Step-by-step explanation:
Given that,
BC = 8 
Ac = 15 
We can find AB using the pythagoas theorem.

We know that,
 , B is base and H is Hypotenuse
, B is base and H is Hypotenuse

Hence, this is the required solution.
 
        
             
        
        
        
Answer:
m∠SRT = 33°     ∵ m∠QRT = m∠SRT
Step-by-step explanation:
Given the diagram,
RT bisects ∠SRQ, and m∠QRT = 33°
RT bisecting ∠SRQ means RT will bisect ∠SRQ into two equal angles, which are:
m∠QRT = m∠SRT
as 
m∠QRT = 33°
so
m∠SRT = 33°     ∵ m∠QRT = m∠SRT
 
        
             
        
        
        
B. 
For all 3 to work together, they can paint 1 room per hour.
C. 
John can paint a room at 1/4 of a room per hour.
Rick can paint a room at 1/5 of a room per hour.
Together they can paint a room at a rate of 9/20 of rooms per hour.
D.
1 = 1/4j + 1/5r + 11/20m (john, rick, molli)
E. 
The least common denominator is 20
F. 
1 = 1/4(0) + 1/5(0) + 11/20x
1 = 0 + 0 + 11/20x
1 = 11/20x
x = 1/(11/20)
x = 1 9/11 
It will take Molli 1 hour and 49 minutes (60 x 9/11) to paint the room alone.
        
             
        
        
        
Answer:
area of this circle: 490.6 inch²
Step-by-step explanation:
area of circle: π(radius)²
Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in
using the formula:
3.14(12.5)²
490.625 inch²
490.6 inch²____rounded to nearest tenth.
