You would use the tangent first, because the opposite of 40 would be x and the adjacent would be 30ft

Answer:
(b) 23
Step-by-step explanation:
The diagonals of a rectangle are the same length, so ...
AC = BD
2x +10 = 56
x +5 = 28 . . . . . divide by 2
x = 23 . . . . . . . . subtract 5
Answer:
⅓x + y = 5⅓
or
⅓x + y = 5.3333333
or
⅓x + y = 16/3
Step-by-step explanation:
Solve for slope using rise/run
Y2 - Y1 / X2 - X1
(6) - (5) / (-2) - (1)
1 / -3
Slope: -⅓
y = -⅓x + b
solve for b using one of the points
I'll be using (1,5)
Substitute the point into the equation
5 = -⅓(1) + b
5 = -⅓ + b (add ⅓ to both sides)
+⅓ +⅓
5⅓ = b
5⅓ can also be written as 16/3 or 5.333333
The equation is now:
y = -⅓x + 5⅓
Convert to standard form by adding ⅓x to both sides
y = -⅓x + 5⅓
+⅓x +⅓x
Solution: ⅓x + y = 5⅓
C, both speed and It’s velocity
total of interior angles for a 6 sided polygon = 720
150 + 152 + 91 +90+90 = 573
x = 720 - 573
x = 147
