It took Mason 9.4 - 2.65 = 6.75 minutes to complete the Second Challenge.
Answer:
IN 10 WEEKS
Step-by-step explanation:
t = time in weeks
150 + 10t = 25t
150 = 25t - 10t
150 = 15t
150/15 = t
10 = t
Each triangle is equal to 180°, and you already have 67° labeled. And the other angle is a right angle which is 90°. So subtract 67 and 90 from 180 to get the angles of 1 and 2 (they are equivalent)
Answer:
0
Step-by-step explanation:
sin²θ + cos²θ = 1
secθcosθ = (1/cosθ)cosθ = 1
1 - 1 = 0
