AfilCa [17]1 year ago

Answer:

18m

Step-by-step explanation:

Since the given traingles are similar

We get

\frac{JK}{MN} =  \frac{KL}{ML}

\frac{JK}{42}  =  \frac{21}{49}

JK =  \frac{21 \times 42}{49}

JK =  \frac{3 \times 7 \times 6 \times 7}{7 \times 7}

JK = 3 \times 6 = 18

JK = 18

Hence the distance across river is 18m

Need help on 9 don’t know if I did it right or not but I need help :p
solmaris [256]

Answer:

9b) -8 = y

9a) 72° = <em>m</em>∠<em>ABC</em>

Step-by-step explanation:

Since you have an angle trisector, in this case, <em>m</em>∠<em>CBE</em><em> </em>≅ <em>m</em>∠<em>DBA,</em><em> </em>therefore you <em>set</em><em> </em><em>x</em><em> </em>equal to 8, plus, according to Morley's Trisector Theorem, all three angles form an equilateral triangle, so <em>m</em>∠<em>BOC</em><em> </em>also has to equal 24°:

{8}^{2}  - 5(8) = 64 - 40 = 24 \\  \\ 6(8) - 24 = 48 - 24 = 24 \\  \\ 2(8) - y = 24 >> 16 - y = 24 >>  -8 = y

Then, <em>m</em>∠<em>ABC</em><em> </em>comes from multiplying 3 by 24 [three <em>twenty-</em><em>four</em>'s], which results in 72°.

I am joyous to assist you anytime.
