I might be wrong but im sure it is equal
Ah usatestprep ok 90% of awnsers are C so pick C
Use the formula....central angle/360= arc length/2* pie* R
150/360=x/2*3.14*7.5
150/360=x/47.1
360x=7065
x=7065/360
x=19.625 in
Answer:
hope this helps
Step-by-step explanation:
For a.) I would do the simplist example possible and make all 3 angles equal. So you would divide 180° degrees by 3. This gives you 60° for each angle. That is still acute.
b.) complementary angles mean they add up to 90°
If one has to be greater than 45° you can so 68° and 22°.
c.) 100 - 10,10; 20,5; 50,2; 4,25
You can choose any pair for the length and width of the ones I put above. :)
d.) angle ABC can equal 32° and angle CBD can be 10°
2+42/-2-5(-3) Multiply -5 and -3.
2+42/-2+15 Now, add the non fraction numbers. (2 and 15)
17+42/-2 Here, you want to reduce the fraction if you can, and yes, you can. Find the divisible number that is the lowest one that both can be evenly divided by. For this problem, it’s -2.
17-21. And from here, its easy. Just a simple subtraction problem.
-4 should be the correct answer.
