Answer:
Step-by-step explanation:
the diameter is the measurement that is all the way across the circle which is given to you so the diameter is 7cm. To find the radius it is half the way across the circle so it is half the diameter so in this case the radius would be 3.5cm
Since sin is opposite/hypotenuse, it can be a/(r+s) since r+s (aka e) is the biggest length in the bigger triangle, h/b since b is the hypotenuse in the right triangle, and the third one is tough - since the triangle with BC as the hypotenuse is similar to the biggest triangle (since e is parallel to s), the angle is either equal to B or C. Since angles B clearly are the same in the biggest triangle and the smallest, that's not possible, so it's angle C. The opposite/adjacent of that is s/a - I challenge you to use this technique for C and D!
