By the property of circle,
(AE)(AD) = (AC)(AB)
=> (x)(x+4) = 3×15
=> (x)(x+4) = 45
=> x = 5
So AE = 5

The AC and DE parts of the cover have an isosceles triangle and the CD parts are rectangular. On the left side of the cover, there is a liquid with a specific gravity & above the B,...
(1 point) С 13 A 9 B If AB has length 9 and BC has length 13, find: • The length of AC: • The measure of angle B (in degrees): • The measure of angle C (in degrees): If you use a calculator to find a decimal approximation, your answer must be accurate to at least 3 decimal places. If you're using a calculator, be sure that your calculator is set to degrees, not radians.

correct incorrect At least one of the answers above is NOT correct. (1 point) Instructions: When entering a number in a blank below, always use a numeral. For instance enter "4" instead of writing "four". Use the HW3 Information Sheet for Axioms and Definitions. When referring to Axiom 2, for example, write a 2. When referring to Definition 4, for example, write d4. When referencing a hypothesis of the theorem you are try to prove, enter "h". You may find...
