The dimension of the yard an shed are shown here . Find a polynomial that describes the area of the lawn that needs to be mowed

Find the area of the yard

Find the area of the shed

Find the area of the lawn by subtracting the shed area from the yard area

there are no figures how am i supposed to answer this question

step-by-step explanation:

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two

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
