Answer:
Step-by-step explanation:
Given
Balloon in the east makes an angle of elevation of and is at height of 461 m
Balloon in the west makes an angle of elevation of and is at height of 296 m
Erica height is 1.6 m tall so net altitude of Red balloon is 459.4 m
and net height of Blue balloon is 294.4 m
using trigonometry
Distance between two Balloons
Answer:
(4, 15)
Step-by-step explanation:
let (x,y) is the mid point of line segment with endpoints (2,14) and (6,19)
we have,
x = (2+6)/2 = 4
y = (14+16)/2 = 15
Hence the midpoint of the line segment with endpoints (2,14), (6,19) is (4,15)

Answer:
a factor of 2 is shown, but 4 was factored out
Step-by-step explanation:
The difference of squares is factored as ...
a² -b² = (a +b)(a -b)
Then the given difference of squares factors as ...
144x² -100 = (12x)² -10² = (12x +10)(12x -10)
Each of these factors has a factor of 2 that can be factored out:
= (2(6x +5))(2(6x -5))
= (2·2)(6x +5)(6x -5)
= 4(6x +5)(6x -5)
The first factor should be 4, not 2.
Answer:
C. HL
Step-by-step explanation:
The diagram given shows that the hypotenuse length and the length of a leg of one right triangle is congruent to the hypotenuse and corresponding leg length of the other. Based on Hypotenus-Leg criterion, the two right triangles is proved to be congruent because it meets the criterion of HL.
