Step-by-step explanation:
1(
m<1= 62°
2)
m<1=90°
3)
180-70-65=45
m<1= 45°
4)
180-90-30=60
m<1= 60°
The length of arc JL is
So option c is correct.
<u>Solution:</u>
Given, from the diagram, radius of the given circle is 2 units.
And, the angle between the radius JK and KL is 125 degrees.
We have to find the length of the minor arc formed by JL
The length of arc is given as:

where
is angle between radii formed by points with centre
Now the length of arc JL is:

Hence, the length of are JL is
so option c is correct.
Answer: 25v+16
Solution: Distribute the -3 to the whole equation in the parenthesis. This will make the equation 27v+12-2(v-2). Do the same thing with the -2 and the other parenthesis. This will make the equation 27v+12-2v+4. Combine like terms. This will make the equation 25v+16.
