So we have a question which is basically related to the trigonometry and geometric combination.
00:08
Part a, we have to find this angle, which is the angle made by two line of sides to the peaks.
00:18
So we know that this complete angle is two pi radiance.
00:24
Okay, so this is complete angle is pi radian.
00:28
So this angle that is assumed this to be theta theta will be equal to pi minus these two angles to 1 .10 plus 0 .84 now pi radian equals to 3 .142 or we can say 3 .14 radiance minus this will be 1 .94 minus 1 .94 which means 1 .20 so that will approximately be equal to 1 .20 radiance.
01:04
This is the answer for part a.
01:08
Now comes part b.
01:10
Part b we have to approximate the amount of vertical climb that is necessary to reach the summit of each peak.
01:18
So basically we have to find these two lengths, these two lengths.
01:24
So if we suppose this to be peak one and this to be peak two, which means if we need to go to peak one, to peak one, which means if we need to go to peak one, so we will be writing we have to find this h1 and h2 h1 is the distance height of the peak 1 so and this is being given and we have to find this and angle is already here so we'll be using sign sign of this 1 .10 radian will be equal to h1 by 6 ,700 so h1 will be equal to h1 will be equal to 6 ,700 feet into sign 1 .10 radiance...
