I got y^2/2

My Solution:

√9^2/18 · y^2

= 1/2 y^2

Multiply Fractions: a · (b/c) = (a · b)/c

 1·y^2/2

=y^2/2

Hope I helped,
Faith xx

Find the value of X and Y ​
gogolik [260]

Answer:

x=54º

y=63º

Step-by-step explanation:

Let the other angle in the triangle be zº.

Because the measure of a line is 180º, zº=180º-117º=63º.

Because the triangle is isosceles yº=zº=63º.

The sum of the measure of the angles in a triangle is 180º. So, 63º+63º+xº=180º.

126º+xº=180º

xº=54º

At an angle of elevation 610
Vadim26 [7]

Answer:

The height of the cliff CD is approximately 539.76 m

Step-by-step explanation:

The given parameters are;

The first angle of elevation with which the captain sees the person on the cliff = 61°

The second angle of elevation with which the captain sees the person on the cliff after moving 92 m closer to the cliff = 69°

The angle made by the adjacent supplementary angle to the second angle of elevation = 180° - 69° = 111°

∴ Whereby, the rays from the first and second angle of elevation and the distance the ship moves closer to the cliff forms an imaginary triangle, we have;

The angle in the imaginary triangle subtended by the distance the ship moves closer to the cliff = 180° - 111° - 61° = 8°

By sine rule, we have;

AB/(sin(a)) = BC/(sin(c))

Which gives;

92/(sin(8°)) = BC/(sin(61°))

BC = (sin(61°)) × 92/(sin(8°)) ≈ 578.165 m

BC ≈ 578.165 m

The height CD = BC × sin(69°)

∴  The height of the cliff CD = 578.165 m × sin(69°) ≈ 539.76 m.

The height of the cliff CD ≈ 539.76 m.

What is the measure of
LenKa [72]

Answer:

C. Ф = 4 radians

Step-by-step explanation:

Given,

Radius of the Circle (r) = 3cm

Length of the Arc (S) = 12cm

In any circle of radius r, the arc length S to the circumference equals the ratio of the angle θ subtended by the arc at the centre and the angle in one revolution. Thus, measuring the angles in radians, S=rθ.

Therefore, S = r*Ф

12 = 3*Ф

Hence, Ф = 4 radians
