Answer:
Step-by-step explanation:
1 hr=60 min
1 km=0.62137 miles
15 km/min=(15×60) km/hr=900 km/hr=(900×0.62137) miles /hr=559.233 miles/hr
The answer is 27 but I am not sure I hope my calculations ain't wrong
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
You can do that by simply measuring the main angle and then measuring each of the two angles. If you bisected the angle correctly, you will find that each of the two angles is equal to half the original.
You can measure the angle by following these steps:
1- Place the straightedge on the base of the angle.
2- Slide the protractor over it until the vertex of the angle is at the zero of the protractor.
3- Measure the angle.
First, distribute the 12
156-168-15=16+4+x
-27=20+x
-47=x
