Answer:
c is correct.
Step-by-step explanation:
First we simplify the expressions of the parties, and when we get to the two fractions, we multiply the cross, and the answer is obtained.
It should be noted that with a few quick calculations the correct option was reached.
Change mixed fraction to improper fraction and also the second fraction has to be reciprocal
Ex- 3/8= 8/3
So now the problem is
13/8*8/3= 13/3 (because you cross divide) Now, turn into fraction
Divide
13 divided by 3= 4 1/3
So your final answer is 4 1/3
Smaller angle = 41°
Larger angle = 139°
Step-by-step explanation:
(7x - 1) + (2x + 1) = 180
7x + 2x - 1 + 1 = 180
9x = 180
x = 20
- The measure of the smaller angle is
2x + 1
= 2(20) + 1
= 40 + 1
<u>= 41°</u>
- The measure of the larger angle is
7x - 1
= 7(20) - 1
= 140 - 1
<u>= 139°</u>
75(π/180) = 5π/12 radians
arc length = central angle (2πr)
360
measure of the inscribed angle = 75º
measure of the central angle = 150º
arc length = 150 (2π1000)
360
arc length = (5/12)(2000π)
arc length = (166 2/3)π meters
