Answer:
A) 150 m
B) 180.28 m
Step-by-step explanation:
A) In order to find the horizontal distance from the base of the cliff to the speed boat, use the Pythagorean theorem to calculate the length of the missing side.
We are told that one of the sides is 80 m and the hypotenuse is 170 m. Therefore,
- a² + b² = c²
- (80)² + b² = (170)²
- b² = 170² - 80²
- b² = 22500
- b = 150
The horizontal distance between the base of the cliff and the boat is 150 m.
B) Now, the side that was 80 m is now 100 m (includes the height that the helicopter is above Jumbo). The horizontal distance remains the same, 150 m, but the hypotenuse is different. Solving for the hypotenuse will give us the distance between the helicopter and the speed boat.
- (100)² + (150)² = c²
- 32500 = c²
- 180.28 = c
The distance between the helicopter and the speed boat is 180.28 m.
Answer:
0. 542
Step-by-step explanation:
Answer:
34 degrees.
Step-by-step explanation:
First of all, the sum of a triangle's degree is 180.
The angle next to the 101 is 79 degree due to the rule of supplementary angle. The angle vertical to 28 is also 28. (Vertical angles are equal).
Now we now the two side, we can figure out the last side.
180-28-79= 73
The last angle is 73 degrees. However, we are looking for x.
x+39=73
All we have to do now is subtract 39 from 73, and that leaves us with 34.
Well, you're given that

. I think the extra information is extraneous, unless there's something more that you forgot to add.
Hope I could be of some assistance. :)
