- Right triangle trigonometrics

Calculate the size of the remaining sides and angles of a right triangle ABC if it is given: b = 10 cm; c = 20 cm; angle alpha = 60° and the angle beta = 30° (use the Pythagorean theorem and functions sine, cosine, tangent, cotangent) - One side

One side is 36 long with a 15° incline. What is the height at the end of that side? - Bevel

I have bevel in the ratio 1:6. What is the angle and how do I calculate it? - Sphere in cone

A sphere is inscribed in the cone (the intersection of their boundaries consists of a circle and one point). The ratio of the surface of the ball and the contents of the base is 4: 3. A plane passing through the axis of a cone cuts the cone in an isoscele - Climb

Road has climbing 1:27. How big is a angle corresponds to this climbing? - Descent of road

Road sign informs the gradient is 10.9%. Calculate the angle which average decreases. - Pilot

How high is the airplane's pilot to see 0.001 of Earth's surface? - Railway

Railway line had on 5.8 km segment climb 9 permille. How many meters track ascent? - Road

The angle of a straight road is approximately 12 degrees. Determine the percentage of this road. - Hole's angles

I am trying to find an angle. The top of the hole is .625” and the bottom of the hole is .532”. The hole depth is .250” what is the angle of the hole (and what is the formula)? - Height difference

What height difference overcome if we pass road 1 km long with a pitch21 per mille? - Inscribed and described circle

Find the radii of a circle inscribed and circumscribed by a regular pentagon whose side measures 3 cm. - The staircase

The staircase has a total height of 3.6 m and forms an angle of 26° with the horizontal. Calculate the length of the whole staircase. - Slope

What is the slope of a line with an inclination 6.06 rad? - Tree

How tall is the tree that observed in the visual angle of 52°? If I stand 5 m from the tree and eyes are two meters above the ground. - Find the

Find the content of a regular 12 sided polygon, if its side a = 12 cm. - Steeple

Steeple seen from the road at an angle of 75°. When we zoom out to 25 meters, it is seen at an angle of 20°. What is high? - n-gon II

What is the side length of the regular 5-gon circumscribed circle of radius 11 cm? - How far
