Answer:
21.99 units
164.93 units²
Step-by-step explanation:
given radius r = 15 units
angle of sector = 84°
Length of sector = x 2 x π x r
= x 2 x 3.14 x 15
= 21.99 units
Area of sector = x π x r²
= x 3.14 x 15²
= 164.93 units²
You need to multiply 2.25 by 80 and it will equal 180 so the answer is....you need to sell 80 keychains. Hope i helped :-)

Answer:
x =
Step-by-step explanation:
in a 30-60-90 triangle the ratio of the side lengths is 1 : 2 :
to find the length of short leg, x, you can create this proportion:
x / 8 = 1 /
cross-multiply to get:
x = 8
x = 8 /
rationalize the denominator by multiplying numerator and denominator by
x =
