Give each side and angle measure rounded to the nearest whole number.

Step-by-step explanation:

By applying sine rule in the given triangle,

cos(25°) =

cos(25°) =

b = 400[cos(25°)]

b = 362.52

b = 363 ft

By applying sine rule in the given triangle,

sin(25°) =

sin(25°) =

a = 400[sin(25°)]

a = 169.05

a = 169 ft

m∠A + m∠B + m∠C = 180°

25° + m∠B + 90° = 180°

m∠B = 180° - 115°

m∠B = 65°

answer: 7 x 2/5 = 2.8 hours, is your answer. your welcome! : 3

step-by-step explanation: first work out how long it took to hose 1/7 of the lawn which is 2/5 hours. times that by 7 to get the whole lawn.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.
