Answer:
<S = 151 degrees
<DCE = 52 degrees
Step-by-step explanation:
The sum of interior angle of pentagon is 540 degrees
5x+2+7x-11+13x-31+8x-19+10x-3 = 540
43x - 62= 540
43x = 540+62
43x =602
x = 602/43
x = 14
get <S
<S = 13x-31
<S = 13(14)-31
<S = 182-31
<S = 151 degrees
2) The sum of interior angle is the exterior
180-7x+2+180-4x-33 = 9x-31
360-11x-31 = 9x - 31
360 = 9x+11x
360 = 20x
x = 360/20
x = 18
<DCE = 180 - 7x - 2
<DCE = 180-7(18)-2
<DCE = 180-126-2
<DCE = 180-128
<DCE = 52 degrees
Answer:
Total distance cover by car = 253.45 km (Approx.)
Step-by-step explanation:
Given:
Speed of car = 45 km/h for 3¾ hour
Distance cover in next 2 hour = 84.7 km
Find:
Total distance cover by car
Computation:
Distance = Speed x time
Distance cover by car = 45 x 3¾
Distance cover by car = 168.75 km
Total distance cover by car = Distance cover by car + Distance cover in next 2 hour
Total distance cover by car = 168.75 + 84.7
Total distance cover by car = 253.45 km (Approx.)
If all the numbers are the property taxes. simply add them up.
11,500 +7,325 + 3,455 = $22,280
Answer:
$165 is the total cost of the first year of Keecia’s gym membership
Step-by-step explanation:
formula for direct proportion : y = kx
x = 50
y = 75
50 = k * 75
k = 75/50
k = 3/2x
substitute y = 60
60 = 3/2x
x = 3/2 * 60
x = 90
$90 + $75 = $165
