Answer:

$C=18.85$

Step-by-step explanation:

C= Circumference

D= Diameter

R= Radius

$\pi =pi$

Diameter of Trampoline= 6

Radius (Diameter divided by 2 or multiplied by 1/2 or 0.5)= 3

$C= 2\pi r \\or\\C= 2\pi (\frac{d}{2})\\C=2\pi (\frac{6}{2})\\C=2\pi3\\C= 6\pi = 18.85$

An isosceles triangle △ABC with the base BC is inscribed in a circle. Find the measures of angles of the triangle, if measure of

____ [38]

Answer:

angle at A: 51°
base angles: 64.5°

Step-by-step explanation:

The measure of the inscribed angle BAC is half the measure of the intercepted arc BC, so is 102°/2 = 51°.

The base angles at B and C are the complement of half this value, or ...

90° -(51°/2) = 64.5°

The angle measures in the triangle are ...

∠A = 51°

∠B = ∠C = 64.5°
