Answer:
Measure of arc ZWX is <u>230°.</u>
Step-by-step explanation:
Given:
arc WX = 50°
Now
The diameter divide a circle into two equal parts
so

Since WZ is diameter of the circle.
substituting in above equation we get

Hence Measure of arc ZWX is <u>230°.</u>

Step-by-step explanation:
Answer:
Step-by-step explanation:
There are 1000 m in 1 km, and 3600 s in 1 h, so the speed conversion is ...

The car's speed is 90 km/h.
__
In 2 hours, the car will travel ...
distance = speed · time = (90 km/h)(2 h) = 180 km
Answer:
37 miles an hour
Step-by-step explanation:
you set up a ratio
100/62 on left 60/x on right
cross mult and get 100x=60(62)
100x=3720
x= 37.2
