Answer:
A: x=16
B: ∠A=22
Step-by-step explanation:
A
The angles in a triangle always add up to 180. Therefore:
∠A+∠B+∠C=180
(2x-10)+(3x)+(4x+46)=180
2x+3x+4x+46-10=180
9x=180-36
x=144/9
x=16
B
∠A=2x-10
∠A=2(16)-10
∠A=32-10
∠A=22
Area = (side)^2
Area = (20cm)^2
Area = 400cm^2 = the area of one square.
Let T = total area
T = 10(Area)
T = 10(400cm^2)
T = 4,000cm^2
Done.
8 is the largest number that goes into both 32 and 40.
40/8 = 5
32/8 = 4
so there can be 8 teams, each consisting of 5 girls and 4 boys
Answer:
Step-by-step explanation:
X-3y=-5x
(-2y)-3y=15(-2y)
-3y=15
y=-5
Answer:total area
32 multiply by 18=576
Then to get the cost of painting you divide 576/50=11.32
Answer 11.32
