AleksAgata [21]

Solution:

Given: ABCD is a Rhombus

To Prove: ΔABC≅ΔCDA

Construction: Join AC as diagonal.

Proof: ABCD is Rhombus whose sides are equal and diagonal are perpendicular bisectors. Please see attach figure.

In ΔABC and ΔCDA

AB=CD           (Side of same Rhombus)

BC=DA           (Side of same Rhombus)

AC=CA           (Common Side of both triangle)

Therefore, ΔABC≅ΔCDA  by SSS property of congruence.

Hence Proved, ΔABC≅ΔCDA

The diameter of a professional baseball mound is 18 feet. The radius of a little league baseball mound is 5 feet. What is the di
alexandr402 [8]

Answer:

175.93 feet

Step-by-step explanation:

First, you divide 18 by 2 to get the radius which is 9. Then you do nine squared. Lastly, you do 64 times 3.14 to get 254.47 (rounded)

Now, you do 5 squared which is 25. Then you multiply 25 by 3.14 to get 78.54 (rounded).

Now you subtract

254.47 - 78.54 = 175.93

Note: I rounded these in the example, the decimal places still go on so the rounded answers may not subtract to the correct answers because all the decimal points weren't shown, but the answer is correct.
