Answer:
106.44 ft
Step-by-step explanation:
tan = opp/adj
tan61 = opp/59
59*tan61 = opp
opp = 106.438817561014012
Rounded
106.44 ft
The angle between two vectors is:
CosФ = u - v / Magnitude(u) x magnitude(v)
Magnitude of u = SQRT(7^2 + -2^2) = SQRT(49 +4) = SQRT(53)
Magnitude of v = SQRT(-1^2 +2^2) = SQRT(1 +4) = SQRT(5)
u x v = (7 x -1) + (-2 x 2) = -7 + -4 = -11
cosФ = -11 / sqrt(53) x sqrt(5)
cosФ = -11sqrt265) / 265
Ф =cos^-1(-11sqrt265) / 265)
Ф=132.51 degrees.

Answer: x = 400 MPH x+60 = 460 MPH
Step-by-step explanation:
(Distance = (Rate)(Time)
Let x = speed of the LA bound plane
Then, x+60 = speed of NYC bound plane
Sum of distances = 2464
3.4x + 2.4(x+60) = 2464
5.8x + 144 = 2464
5.8x = 2320
x = 400 MPH x+60 = 460 MPH
GH GI and HI are parallel to CB, AB and AC respectivele
m< A = 180 - 40 - 61 = 79 degrees
m < IHB = 79 ( < A and <IHB are corresponding angles)
and m < x = m < IHB) = 79 degrees ( < x and < IHB are internal alternate angles)
Answer is 79 degree
