mCD=77°

Step-by-step explanation:

-The measure of the arc angle subtending from the diameter adds up to 180° .

-Given mAD=(19x – 49)° and mCD = (5x + 37)°, we equate their sums to 180°  and solve for x:

Hence, mCD=77°

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
