Find the measure of angle b, note that angle b is acute

B= 44.9506°

Step-by-step explanation:

WE apply sine angle formula

Given angle C = 51, c= 11 and b = 10

Plug in the values

Cross multiply it

10 * sin(51) = 11* sin(B)

7.771459615 = 11 sin(B)

Now divide by 11 on both sides

0.706496328 = sin(B)

Now

B= 44.9506°

answer:

it will cost 480 dollars to refurbish the larger wood floor

step-by-step explanation:

as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio

384 / 4 = 96 dollars

96 dollars per unit of the ratio

now to get the price to refurbish the larger wood floor, times the price by the units

96 * 5 = 480

it 2

step-by-step explanation:

8^1/3=2
