Answer:

sin(θ) = sin(θ + 2π) = -sin(-θ)

b and d

This can be shown by substituting a value for θ

sin(π ÷ 3) = 1/2

sin(π ÷ 3 + 2π) = 1/2

-sin(π ÷ 3) = -1/2

-sin(-π ÷ 3) = 1/2

sin(π ÷ 3 + π ÷ 2) = √3/2

You could expect about 1,248 students to play at least 4 hours every week.

Our tables have 100 students involved. All but 4 of the students are in the category of at least 4 hours. That is 96%.

Therefore, we simply need to multiply 0.96 by 1300 to get the estimated amount.

0.96 x 1300 = 1248

Which set of angle measures could be the interior angles of a triangle?
andriy [413]

Answer:

d. 15, 30, 135

Step-by-step explanation:

A triangle's interior angles on a flat surface add up to 180 degrees.

a. 90 * 3 = 270 != 180

b.(80 * 2) + 200 = 360 != 180

c.40 + 50 + 60 = 160 != 180

d.15 + 30 + 135 = 45 + 135 = 180, so it has to be d.
