Question

FAST ANSWERS ONLY 59. A triangle has sides of lengths 21, 47, and 52. Is it a right triangle? Explain.A. yes; 212 + 472 € 522C. yes; 212 + 472 522B.no; 212 + 472522D. no; 212 + 472 522

Answer 1

The largest side of the triangle is 52.

Checking pythagoraus theorem,

`\begin{gathered} 52^2=2704 \\ 21^2+47^2=441+2209 \\ =2650 \\ \text{Thus,} \\ 21^2+47^2\\e52^2 \end{gathered}`

Thus, it is not a right angle triangle.

Thus, option (D) is correct.
