Answer:
 = 130°
 = 130°
Step-by-step explanation:
Angles subtended at the center by the arcs  and
 and  are ∠HPG and  ∠EPF.
 are ∠HPG and  ∠EPF.
Since these angles are the vertical angles both will be equal.
m∠HPG ≅ m∠EPF
3x - 10 = 2x + 10
3x - 2x = 10 + 10
x = 20
Therefore,  
 
                                = 50°
Similarly  = 50°
 = 50°
In the same way angles subtended at the center will be equal.
m∠EPH ≅ m∠FPG
and 
Since  °
°



Therefore, measure of arc EH = 130°
 
        
             
        
        
        
Answer:
216 people
Step-by-step explanation:
Given:
2.5 feet² is occupied by 1 person
Dimension of room = 216 in × 360 in
Required:
No. of people that would occupy the room
SOLUTION:
Step 1:
Convert the dimensions of the room from in to ft
Note: 1 foot = 12 inches 
216 inches = 
360 inches = 
Step 2: calculate area of the room.
Area of the room = 30*18 = 540 ft²
Step 3: calculate the no. of people the room will contain.
2.5 ft² will contain one person
Therefore, 540 ft² will contain:

Answer:
352 ft (squared)  , he will need 12 paint cans 
Step-by-step explanation:
Two 12 by 8ft walls = 192 ft in area, Two 10 by 8ft walls = 160 ft in Area, that equals 352 ft total, 352/30=11.73 repeated, round up to 12
 
        
             
        
        
        
Answer:
first open the bracket by multiplying 28 by 4 which is equal to 112, then add it to 18 which be equal to 130 which is the final answer
