Answer: Angle A = 120° and angle C = 45°
Step-by-step explanation: The first thing to note at the back of our minds is that the sum of the interior angles of a triangle equals 180°. Given that the three angle are available, we can start by adding them all together. Hence,
{12x + 12} + 15 + {3x + 18} = 180
12x + 12 + 15 + 3x + 18 = 180
By collecting like terms, we arrive at,
12x + 3x + 12 + 15 + 18 = 180
15x + 45 = 180
Subtract 45 from both sides of the equation
15x = 135
Divide both sides of the equation by 15
x = 9
At this point, we can now substitute for the value of x = 9 in the expressions representing angles A and C.
Angle A = 12x + 12
= 12(9) + 12
= 108 + 12
= 120
Angle A = 120°
Angle C = 3x + 18
= 3(9) + 18
= 27 + 18
= 45
Angle C = 45°
17 = p - 3 - 3p
17 = -2p - 3
17 + 3 = -2p
20 = -2p
-20/2 = p
-10 = p <==

Answer:
Angle of elevation at which the balloon must take off in order to avoid hitting the tree is 5 degrees
Step-by-step explanation:
Given:
The height of the tree = 65 foot
The distance between the tree and the spot from which the balloon is launched = 250 yards
To find:
The angle of elevation at which the balloon must take off in order to avoid hitting the tree = ?
Solution:
Converting the yards to feet
1 yards = 3 feet
250 yards = 3 x 250 = 750 yards
Refer the below figure, The angle x is the angle of elevation at which the the ball must be thrown so that it does not Hit the tree
Substituting the values
