Let KLMN be a trapezoid (see added picture). From the point M put down the trapezoid height MP, then quadrilateral KLMP is square and KP=MP=10.
A triangle MPN is right and <span>isosceles, because
</span>m∠N=45^{0}, m∠P=90^{0}, so m∠M=180^{0}-45^{0}-90^{0}=45^{0}.Then PN=MP=10.
The ttapezoid side KN consists of two parts KP and PN, each of them is equal to 10, then KN=20 units.
Area of KLMN is egual to

sq. units.
Given the system of the equation below;

We can use the elimination method to solve the systems of equations
Step 1: Subtract equation 2 from equation 1 and solve for x

Step 2: Sustitute x = 1 in equation 1

Therefore, the solution to the system of equation is
Answer:
25x
Step-by-step explanation:
6x + 19x = 25x
The probability is 7/10 that it doesn't hit her.
