Question

NEED ANSWER ASAP REALLY IMPORTANT i will take any of the answers

Answer 1

`1. \: MC \: is \: tangent \: to \: (B)\Rightarrow \widehat{BCM}=90° \\ 2. \: MC \: and \: MZ \: are \: tangent \: to \: (B)\Rightarrow MC = MZ\Leftrightarrow 5x - 9 = x + 7\Leftrightarrow x = 4 \\ 3. \: BM = \sqrt{ {BC}^(2) + {MC}^(2) } = \sqrt{ {5}^(2) + {12}^(2) } = 13 \\ \Rightarrow EM = BM - BE = BM - BC = 13 - 5 = 8 \\ 4. \: \tan(60°) = (MC)/(BC) = (13 √(3) )/( BC)\Leftrightarrow BC = (13 √(3) )/(\tan(60°)) = (13 √(3) )/( √(3) ) = 13 \\ 5. \: MC = \sqrt{ {BM}^(2) - {BC}^(2) } = \sqrt{ {20}^(2) - {12}^(2) } = 16 \\ 6. \:BZ = \sqrt{ {BM}^(2) - {MZ}^(2) } = \sqrt{ {25}^(2) - {20}^(2) } = 15 \\ \Rightarrow XE=BX+BE=BZ+BZ=15+15=30`
