Finding side length of the 90-degree angle triangle

Mathematics
1 answer:
allsm [11]3 years ago
8 0

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin45° = \frac{1}{\sqrt{2} }

sin45° = \frac{opposite}{hypotenuse} = \frac{x}{4\sqrt{2} } = \frac{1}{\sqrt{2} } ( cross- multiply )

\sqrt{2} x = 4\sqrt{2} ( divide both sides by \sqrt{2} )

x = 4

Apyramid was built about 2570 BC. Its original height was 453 feet, 11 inches, but
sweet [91]

Answer:

  422.44 feet

Step-by-step explanation:

Let A, B, X, and H represent the left-most observation point, the observation point to its right, the point immediately below the apex, and the height of the apex, respectively.

Then the definition of the cotangent function tells us ...

  AX = H·cot(42°)

  BX = H·cot(48.85°)

Since the figure tells us AB = 100 feet, we have ...

  AB = AX -BX

  100 = H·cot(42°) -H·cot(48.85°)

  H = 100/(cot(42°) - cot(48.85°)) ≈ 422.44 . . . . ft

The current height of the pyramid is 422.44 feet.

PLS HELP (AGAIN) ILL MARK BRAINLIEST. I HAVE TO TURN THIS IS ASAP
valina [46]

Step-by-step explanation:

A diameter spans from one end of (in this case, a circle) to the direct opposite end, going through the center-point. The radius, on the other hand, is half of a diameter, and spans only from the center-point to a point on the circle.

In this case:

1) Diameter = 18 km (given)

  Radius = 18/2 = 9 km

2) Diameter = 1 x 2 = 2 m

   Radius = 1 m (given)

3) Diameter = 17 x 2 = 34 cm

   Radius = 17 cm (given)

4) Diameter = 50 mm (given)

  Radius = 50/2 = 25 mm

John has a swimming pool, in which the center of the pool to the edge is 3 meters. What is the diameter? Simply multiply 3 with 2:

3 x 2 = 6 meters

6 meters is the diameter.
