<h3>Given</h3>
trapezoid PSTK with ∠P=90°, KS = 13, KP = 12, ST = 8
<h3>Find</h3>
the area of PSTK
<h3>Solution</h3>
It helps to draw a diagram.
∆ KPS is a right triangle with hypotenuse 13 and leg 12. Then the other leg (PS) is given by the Pythagorean theorem as
... KS² = PS² + KP²
... 13² = PS² + 12²
... PS = √(169 -144) = 5
This is the height of the trapezoid, which has bases 12 and 8. Then the area of the trapezoid is
... A = (1/2)(b1 +b2)h
... A = (1/2)(12 +8)·5
... A = 50
The area of trapezoid PSTK is 50 square units.
Answer:
<h2>The probability of first one to be blue is
.</h2>
Step-by-step explanation:
In the given box, there are 4 red markers and 2 blue markers.
The given scenario will not affect the required probability as the selection of the second one is a case of future.
We need to find the probability of the first marker is blue.
The probability is 
.
Yo sup??
M(3,4)
one end is U(7,5)
let the other point be T(x,y)
we know that
x+7/2=3 and y+5/2=4
x=6-7 and y=8-5
x=-1 and y=3
therefore T has coordinates (-1,3)
Hope this helps

Answer:
(-3, 8)
Step-by-step explanation:
For m the midpoint of xy, we have ...
m = (x+y)/2 ⇒ y = 2m-x
y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)
y = (-3, 8)
