Answer:

C

Step-by-step explanation:

<1+<2=180 (angle addition postulate)

<1=39 (given)

39+<2=180 (substitution property)

<2=180-39 (subtraction property)

<2=141 ( simplification)

C, or 141 degrees. Have a nice day!

Monica wants to measure the dimensions of her rectangular lawn. If the longer side of the lawn is (x + 3) feet and the diagonal
Nikolay [14]

Answer:

\text{Hence, The shortest side of her Lawn is} \sqrt{2x+7}\text{ feet}

Step-by-step explanation:

Given: Monica wants to measure the dimensions of her rectangular lawn.

If the longer side of the lawn is BC=(x + 3) feet.

If the diagonal length is AC=(x + 4) feet.

Let the shortest side of lawn is AB=y feet

The angle of rectangle is right angle.

Using diagonal, shortest and longer side to make a right angle triangle whose hypotenuse is length of diagonal.

Using Pythagoreous theorem,

AB^2+BC^2=AC^2

y^2+(x+3)^2=(x+4)^2

y^2=(x+4)^2-(x+3)^2

y^2=x^2+16+8x-x^2-9-6x

y^2=2x+7

y=\pm \sqrt{2x+7}

We will ignore the negative value because side of rectangle can't be negative.

y=\sqrt{2x+7}\text{ feet}

\text{Hence, The shortest side of her Lawn is} \sqrt{2x+7}\text{ feet}
