ludmilkaskok [199]

Given:

The bases of trapezoid measuring 4 m and 12 m.

To find:

The median of the trapezoid.

Solution:

The median of the trapezoid is the average of its bases.

\text{Median}=\dfrac{\text{Upper base + Lower base}}{2}

The bases of trapezoid measuring 4 m and 12 m. So, the median of the trapezoid is:

\text{Median}=\dfrac{4+12}{2}

\text{Median}=\dfrac{16}{2}

\text{Median}=8

Therefore, the correct option is C.

I’m a bit confused on how to solve this problem, and could use some help!
weqwewe [10]

Answer:

Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!

Monica wants to measure the dimensions of her rectangular lawn. If the longer side of the lawn is (x + 3) feet and the diagonal
Juliette [100K]
Let us try and solve it analytically. We have that the side=x+3  together with the short side=s and the diagonal=x+4 satisfy the Pythagorean Theorem. Then we have that (x+4)^2=(x+3)^2+s^2. This yields s^2+x^2+6x+9=x^2+8x+16
which yields s^2=2x+7, hence a) is the correct answer.
