Simply let the angle of elevation be 'x'°.
Therefore, the answer of the given question = x°
Answer:80% of 90 is bigger
Step-by-step explanation:
80% of 90
N= 90/100×80
N= 90/100× 80/100
N=7200/100
N=72
So 80% of 90 is 72
1/2 of 140
70+70=140
So half of 140 is 70.
Using pythagorean identity:
Divide both sides by cos²:
Replace the given values:
Answer:
Answer: 2300.
Explanation:
There are 1000 millimeters in a meter.
There are 100 centimeters in a meter.
There are 10 millimeters in a meter.
Multiply the number of meters by 1000 giving us 2000.
Multiply the number of centimeters by 100 giving us 300.
Add the numbers together to get 2300.
Bonus info
Milli: 1000
Centi: 100
That information should probably help you with other measurement conversions when you take chemistry or physics.
Have a nice day! :) Good luck with the rest of middle school.
