Help please,,
KiRa [710]

Answer:

4. tan(D)=7/24 ≈ 0.2917

    tan(F)=24/7 ≈ 3.4286

6. tan(K)=3/5=0.6000

   tan(J)=5/3 ≈ 1.6667

Step-by-step explanation:

The tangent is the side opposite of the angle divided by the side adjacent to the angle.

4. tan(D)=7/24 ≈ 0.2917

EF  is opposite to D and has length 7. The adjacent side is the side forming the angle that is not the hypotenuse, so it's DE and the length is 24 units.

Do the same thing for the rest of the angles. (You probably already know that acute angles are smaller than 90 degrees, so you have to find the tangent of 2 angles in each problem.) I just used a calculator to divide, but you could do it by hand, and I'm guessing you know how to round. Hope I could help!

Triangle abc has vertices located at a( 0, 2), b (2,5), and c (-1,7). find the length of each side of the triangle
lapo4ka [179]

ab=\sqrt{(0-2)^{2}+(2-5)^{2}}=\boxed{\sqrt{13}}\\\\bc=\sqrt{(2-(-1))^{2}+(5-7)^{2}}=\boxed{\sqrt{13}}\\\\ac=\sqrt{(0-(-1))^{2}+(2-7)^{2}}=\boxed{\sqrt{26}}
