Answer:

x = 25

Step-by-step explanation:

Equiangular triangle is also equilateral triangle.

This means their sides are of equal length.

So, AB = BC = AC

Consider AB = BC

3x - 5 = 2x + 20

3x - 2x = 20 + 5

x = 25

Check:

Length of AB = 3x - 5 = 3(25) - 5 = 75 - 5 = 70

Length of BC = 2x + 20 = 2(25) + 20 = 50 + 20 = 70

Length of AC = 4x - 30 = 4(25) - 30 = 100 - 30 = 70

Step-by-step explanation:

Answer:

The length of a 180° arc of a unit circle is π ≈ 3.14 units.

Step-by-step explanation:

Use your knowledge of the circumference of a circle (the length full around) and the fact that there are 360° in the central angle of a full circle. The distance around is proportional to the angle, so an arc of measure 180° will have a length equal to

... (180°/360°) × circumference = (1/2)×circumference

For a unit circle, the circumference is 2π (= π×diameter = 2π×radius). Half that length is π units.
