Answer:

Yes

Step-by-step explanation:

( {12.5)}^{2}  = 156.25...(1) \\ ( {7.5)}^{2}  + ( {10)}^{2}    \\ = 56.25 + 100  = 156.25...(2) \\ from \: equations \: (1) \: and \: (2) \\ ( {12.5)}^{2}  =( {7.5)}^{2}  + ( {10)}^{2}   \\  \therefore \: given \: side \: lengths \: form \: right \: \\triangle \\ (by \: converse \: of \: pythagorean \:  \\ theorem)

Need with number 7!
topjm [15]

Answer: 6

SOLUTION

∵segment\frac{}{AB}is tangent to the circle at point C.

∴∠MCA=∠MCB=90°

Suppose \frac{}{MC} =x

From the Pythagorean theorem

MA²=9²+x²

MB²=4²+x²

∴MA²+MB²=AB²

i.e. x^{2} +9^{2} +4^{2} +x^{2} =(9+4)^{2} \\2x^{2} +97=169\\2x^{2} =72\\x^{2} =36\\x=6

We conclude that x=6=\frac{}{MC}

Help me with these two
slavikrds [6]
To find the answer of the first one, plug in numbers for x, and see if they make the inequality true. Like, 5, 6, and 7.

For the second one, add 13 to both sides. The answer is 21.
