Answer:
Angle 1 = 108°
Angle 2 = 72°
Angle 3 = 120°
Angle 4 = 96°
Angle 5 = 144°
Step-by-step explanation:
We need to find the measures of the interior angles in a pentagon if the measure of each consecutive angle is in the ratio 9:6:10:8:12.
Let x be the common ratio
So, we can write:
Angle 1 = 9x
Angle 2 = 6x
Angle 3 = 10x
Angle 4 = 8x
Angle 5 = 12x
We know that the <em>sum of all angles of pentagon = 540</em>
So, adding all angles and equal them to 540, we can find value of x
So, we get the value of x: x=12
Now, calculating the angles by putting x=12:
Angle 1 = 9x = 9(12) = 108°
Angle 2 = 6x = 6(12) = 72°
Angle 3 = 10x = 10(12) = 120°
Angle 4 = 8x = 8(12) = 96°
Angle 5 = 12x= 12(12) = 144°
Answer:
230 5/9

slope = (-3 - 4) / (0 - (-3) = -7/3 <=
Answer: 352 miles
Step-by-step explanation:
At the point where the car overtook the bus, the car and the bus would have travelled the same distance.
Let x represent the distance covered by bus and the car before the car overtook the bus.
Let t represent the time taken by the bus to travel x miles.
The bus was traveling at 64 km an hour.
Distance = speed × time
Distance travelled by the bus in t hours would be
x = 64 × t = 64t
if the bus has a 1.5 hour Headstart, it means that the car started moving 1.5 hours after the bus has moved.
Therefore, time spent by the car would be t - 15 hours.
The car traveling at 88 km an hour
Distance covered by the car in t - 1.5 hours would be
x = 88(t - 1.5) = 88t - 132
Since the distance covered is equal, then
88t - 132 = 64t
88t - 64t = 132
24t = 132
t = 132/24
t = 5.5 hours
Therefore, the distance from the starting point when the car overtook the bus would be
x = 64 × 5.5 = 352 miles
