A plane flies 1.4 hours at 150 mph on a bearing of 10. It then turns and flies hours at the same speed on a bearing of . How far
Gnesinka [82]

Answer:

The answer is "1035.76 miles"

Explanation:

The aircraft flies at 120 mph for 1.5 hours at a 10^{\circ} bearing, then flies at the very same speed at 100^{\circ} bearings for 8.5 hours.

However an angle of 100-10 = 90^{\circ} between displacements

First shifts= 1.5 \times 120 = 180\  miles.

Second shift = 8.5\times 120 = 1020\ miles.

These two shifts are at 90^{\circ} and therefore the final shift is:

\to \sqrt{180^2+1020^2}=1035.76 \ miles

PLEASE PLEASE HELP. I will make you brainlest.
zvonat [6]

Answer: 15 √ 2

Step-by-step explanation:

Equilateral triangles have three equal side lengths, three equal angles of 60 degrees, and three equal altitudes.

You would think that the height of an equilateral triangle would also be equal to it's sides, but it's not. The formula for height is: side/2 x √3

10√6 / 2 * √ 3 = 15 √ 2

The decimal form: 21.2

Use the Exterior Angle Theorem to find the measure of each angle.
navik [9.2K]

Answer:

∠ C = 36°

∠ D= 81°

∠ DEC= 63°

Step-by-step explanation:

<em>The exterior angle of a triangle is equal to the sum of the interior opposite angles. </em>

<em />

∴   (11y + 4) + (5y + 1) = 117

         11y + 4 + 5y + 1 = 117

         16y + 5 = 117

         16y = 117-5

         16y = 112

         y = 112÷16

         y = 7

∠ C = 5×(7) + 1 = 36°

∠ D = 11×(7) + 4 = 81°

∠ DEC = 180- 117 = 63°
