Hi!! Can I please have some help with the following trig qs pls:) I’d really appreciate it if anyone could draw me any relevant diagrams when helping me w these qs:

1. From point A, 93m due south of the base of a tower, the angle of elevation is 35 degrees. Point B is due 124m due east of the tower. Find:
a) the height of tower
b) the angle of elevation of tower from point B

2. A cable car 100m above the ground is seen to have and angle of elevation of 65 degrees when it is on a bearing of 345 degrees. After a minute, it has an angle of elevation of 69 degrees and is in a bearing of 025 degrees. Find:
a) how far it travels in that minute
b) it’s speed in ms^-1

3. David walks along a straight road. At one point he noticed a tower on a bearing of 053 degrees with an angle of elevation of 21 degrees. After David walks 230m, the tower is on a bearing of 342 degrees with an angle of elevation of 26 degrees. Find the height of the tower.

THANKS GUYS!!!
