Answer:
arc KLJ = 205°
Step-by-step explanation:
Recall: measure of arc equals measure of central angle
Therefore:
measure of arc LJ = 56°
measure of arc KL = 149°
arc LJ + arc KL = arc KLJ
Substitute
56° + 149° = arc KLJ
205 = arc KLJ

1/4 x 1/20
b, a, e, h, f
just test each variable
you can skip the ones that seem obviously wrong, like c, when you figure out the pattern.
b. |-5|=|-5|
g. |-3|≠|6|
a. |3|=|3|
e. |6|=|6|
j. |2|≠|-3|
h. |6|=|-6|
f.|-3|=|-3|
428.7 mm²
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² ×
= π × 17² ×
= 289π ×
= ≈ 428.7 mm²
12r - 8 - 12
you have to combine like terms. below i have bolded the like terms:
together it combines to:
12r - 20
