Answer: x=3 and y=5
Step-by-step explanation: 11x-6y=3, 5x-8y=-25
11x-6y+6y=3+6y
11x/11=3/11+6y/11
x=3+6y/11
5(3+6y/11)-8y(11)/11
5(6y+3)-88y/11
30y+15-88y/11
88y-30y
58y
11(15-58y)/11=11(-25)
15-58y-15=-275-15
-58y/-58=-290/-58
y=5
x=3+6(5)/11
3+30
33
33/11
x=3
x=3, y=5
option C is the correct answer. sin β = 15 / 17
<h3>How to work it</h3>
<u>Given data</u>
Right angled triangle has sides
opposite = 15
adjacent = 8
Hypotenuse = 17
sin β = opposite / hypotenuse
substituting the values gives
sin β = 15 / 17

Answer:
Step-by-step explanation:
Answer:
390 ft^2
Step-by-step explanation:
We will break this shape into two rectangles, one that is 7 ft wide by 30 ft long
and the other that is 25ft-7ft wide by 30ft -20 ft long (18 ft by 10 ft)
1st: 7 ft by 30 ft
A = l*w = 7*30 = 210 ft^2
2nd: 18 ft by 10 ft
A = l*w = 18 * 10 = 180 ft^2
Add the areas together
210+180 = 390 ft^2
