- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define</u>
∅ = 40°
opposite leg of angle = 50 ft
hypotenuse = x ft
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin40° = 50/x
- Multiply <em>x </em>on both sides: xsin40° = 50
- Divide sin40° on both sides: x = 50/sin40°
- Evaluate: x = 77.7862
- Round: x = 77.8 ft
Answer:
like here x= 3 and y= -15
here, its 5 times goes in negative
now if y = 10 TO X IS 5 TIME POSITIVE HERE = 10×5 = 50
Answer:
c = -2
Step-by-step explanation:
Given equation is :
4(3+c)+c=c+4
12 + 4c + c = c + 4
12 + 4c = 4 [dividing by 4]
3 + c = 1 [adding and subtracting 3]
c = -2
