Answer:
Use tan trig ratio:

where
is the angle, O is the side opposite the angle, and A is the side adjacent the angle
Given:
= 39°- O = 10
= A
Substituting these values into the formula:

Multiplying both sides by
:

Dividing both sides by
:



Answer: 9°
Step-by-step explanation:
(3w + 7)° + 90° + (7w - 7)° = 180°
=> 3w + 7 + 90 + 7w - 7 = 180
=> 10w + 90 = 180
=> 10w = 180 - 90 = 90
=> w = 90 / 10 = 9°
Answer:
0.25
Step-by-step explanation:
Givens
orange: 75
Blue: 62
Green: 52
Red: x
Total: 252
Equation
75 + 62 + 52 + x = 252 Collect the like terms on the left.
Solution
189 + x = 252 Subtract 189 from both sides
x = 252 - 189
x = 63 Red Ones
Probability
P(Red) = 63/252
P(Red) = 0.25
Sum would be equal to 720.
so, x-60 + x-40 + 130 + 120 + 110 + x-20 = 720
3x + 240 = 720
3x = 720 - 240
x = 480/3
x = 160
Angle F = x-20 = 160 - 20 = 140
In short, Your Answer would be 140
Hope this helps!
