Maryam's rectangular bedroom is 9 feet by 12 feet. What is the diagonal distance from one corner to the opposite corner?

1 answer:

4 0

Create a right triangle with the the two legs being sides of 9 and 12...then use the Pythagorean theorem to solve

a^2 + b^2 = c^2

9^2 + 12^2 = c^2
81 + 144 = c^2
225 = c^2

Square root both sides to get c = 15 feet.

Find the midpoint of the segment with the given endpoints. (9.-9) and (2.-10)

kondor19780726 [428]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{(5.5 \: , \: - 9.5)}}}}}$

Step-by-step explanation:

Let the points be A and B

Let A ( 9 , -9 ) be ( x₁ , y₁ ) and B ( 2 , - 10 ) be ( x₂ , y₂ )

Finding the midpoint

$\boxed{ \sf{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} }}$

$\longrightarrow{ \sf{midpoint = ( \frac{9 + 2}{2} , \: \frac{ - 9 + ( - 10)}{2}}} )$

$\longrightarrow{ \sf {midpoint = ( \frac{11}{2} \: , \: \frac{ - 9 - 10}{2}})}$

$\longrightarrow{ \sf{midpoint = (5.5 \: , \: \frac{ - 19}{2}}} )$

$\longrightarrow{ \sf{midpoint = (5.5 \: , - 9.5}})$

Hope I helped!

Best regards! :D
