Let us break the shape into two triangles and solve for the unknowns.

The first triangle is shown below:

We will use the Pythagorean Theorem defined to be:

\begin{gathered} c^2=a^2+b^2 \\ where\text{ c is the hypotenuse and a and b are the other two sides} \end{gathered}

Therefore, we can relate the sides of the triangles as shown below:

25^2=y^2+16^2

Solving, we have:

\begin{gathered} y^2=25^2-16^2 \\ y^2=625-256 \\ y^2=369 \\ y=\sqrt{369} \\ y=19.2 \end{gathered}

Hence, we can have the second triangle to be:

Applying the Pythagorean Theorem, we have:

22^2=x^2+19.2^2

Solving, we have:

\begin{gathered} 484=x^2+369 \\ x^2=484-369 \\ x^2=115 \\ x=\sqrt{115} \\ x=10.7 \end{gathered}

The values of the unknowns are:

\begin{gathered} x=10.7 \\ y=19.2 \end{gathered}

The length of AD is 75. Since opposite sides have the same length, 63 plus 63 is 126. The perimeter is 276, so 276 minus 126 is 150. 150 divided by 2 is 75.

blsea [12.9K]

b^m\cdot b^n=b^{n+m}


Answer: C. b^m+n


Example

2^3\cdot2^4=(\underbrace{2\cdot2\cdot2}_{3})\cdot(\underbrace{2\cdot2\cdot2\cdot2}_{4})=\underbrace{2\cdot2\cdot2\cdot2\cdot2\cdot2\cdot2}_{3+4=7}=2^7:

Answer:

y = 1/2x + 2

Step-by-step explanation:

m = -2, (3, - 1)

y - - 1 = -2(x - 3)

y + 1 = -2x +3

y = - 2x + 2

Perpendicular line slope: 1/2x

y = 1/2x +2
