ABCD is a rectangle. Find the length of segment AC
Oksana_A [137]

Answer:

52

Step-by-step explanation:

First, find x. As BE and DE will have the same measurements, you can set your formula up as

5x+11=3x+17

5x=3x+17-11

5x-2x=6

2x=6

x=6/2

x=3

CE and AE will also have the same value, now substitute 3 in place of x to get the value of segment BE

5x+11

5*3+11 = 26

This also means that CE = 26 and AE = 26

AC = CE + AE

AC = 52

PLEASE HELP ASAP!!! I NEED CORRECT ANSWERS ONLY PLEASE!!!
Elenna [48]

Answer:

cos(V)=\frac{39}{89}=.44

∠V=64.01°

Step-by-step explanation:

sin(angle)=\frac{opposite}{hypotenuse}

cos(angle)=\frac{adjacent}{hypotenuse}

tan(angle)=\frac{opposite}{adjacent}

  • The cosine of an angle is equal to the side adjacent to the angle over the hypotenuse, the longest side.
  • With this in mind:

cos(V)=\frac{39}{hypotenuse}

  • We need to find the hypotenuse of this triangle. This is relativly easy to do with a right triangle; we can just use the Pythagorean Theorem.
  • Pythagorean Theorem: a^2+b^2=c^2  where a, b, and c are the 3 different sides of a right triangle.

a^2+b^2=c^2\\(39)^2+(80)^2=c^2\\1521+6400=c^2\\c=\sqrt{7921} \\c=89

  • Our hypotenuse is 89. Now we can finish solving for ∠V.

cos(V)=\frac{39}{89}\\V=cos^-^1(\frac{39}{89})\\

∠V=64.01°
