In ΔKLM, the measure of ∠M=90°, the measure of ∠K=85°, and MK = 6.9 feet. Find the length of KL to the nearest tenth of a foot.
liq [111]
First take 180-90-85=5 for L angle then we can take tan(85)=ML/6.9, 6.9(tan(85))=ML. So ML=78.87ft. Now we can use Pythagorean theorem to find our KL so KL = sqrt((78.87)^2+(6.9)^2) and we get our answer KL=79.17ft. Hope it helps

satela [25.4K]

Answer:

\left \{ {{y=-1} \atop {x=-4}} \right.

Step-by-step explanation:

\left \{ {{y=\frac{3}{4} x+2} \atop {5x+4y=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+4*(\frac{3}{4}x+2)=-24 }} \right. \left \{ {{y=\frac{3}{4}x+2 } \atop {5x+3x+8=-24}} \right.  \left \{ {{y=\frac{3}{4}x+2 } \atop {8x=-32}} \right. \\\left \{ {{y=\frac{3}{4}x+2 } \atop {x=-4}} \right.  \left \{ {{y=\frac{3}{4}*(-4)+2 } \atop {x=-4}} \right.  \left \{ {{y=-3+2} \atop {x=-4}} \right. =>\left \{ {{y=-1} \atop {x=-4}} \right.
