3. You have two triangles. A triangle is at the top of the building, the other is at the top of the mast.
Call the height of the building "B" and the mast height "m".
Triangle 1: one leg is 750 meters, the other leg is B feet and has an angle of 34 degrees.
Tan 34 = b/750
b = 750 (tan 34)
Triangle 2: one leg is 750 meters, the other (b + m) feet and an angle of 50 degrees.
So 50 = (B + M) / 750
B + M = 750 (tan 50)
M = 750 (tan 50) - b
M = 750 (tan 50) - 750 (then 34)
M = 750 (Tan 50 - Tan 34)
M = 750 (1.19175 to 0.674508)
M = 750 (0.517245)
M = 387.9338 = 388 m
4. Not sure, sorry. Looks like you're missing information.

You need to connect to a computer. If you do not have degrees / minutes / seconds, you can up to 34 minutes to a decimal by calculating 34/60.
SEC (488d 34m) = SEK (488.566666 degrees)
= 1 / cos (488.5666666)
= -1.60404
17.
First, find the slope:
m = Y1 (- Y2) / (x1 - x2)
= (5 - 0) / (-3 - 2)
= 5 / (-5)
= -1
Now use one of the dice and write the slope of the equation.
y - y1 = m (x - x1)
and - 0 = (-1) (x - 2)
y =- x + 2
For 18 to 21:
Quadrant 1 is between 0 and 90 degrees
Quadrant 2 is 90 to 180
Quadrant 3 is 180 to 270
Quadrant 4 is 270 to 360
1.
180 degrees = pi
270 = 180 + 90 = p + (pi / 2) = 3pi / 2
