A rectangle has an area of 368.4 in2, and its height is 15 in. Find the base of the rectangle. A/24.56 in

B/25.64 in

C/26.45 in

D/ 24.56 cm

y=mx+b

step-by-step explanation:

m slope

b y-intercept

∠cbe and ∠deb are same-side interior angles.

i took the test

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92
