Answer:

x = 50°

y = 50°

z = 80°

Step-by-step explanation:

working out x:

angles on a straight line add up to 180°

x + 130° = 180°

subtract 130 on both sides

x = 180° - 130°

x = 50°

working out y:

two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°

y = 50°

working out z:

the sum of a triangle add up to 180°

add up the angles of x and y and equate to 180°

50 + 50 + z = 180

100 + z = 180

subtract 100 on both sides

z = 180 - 100

z = 80°

Pavel [41]

Let X and Y be random variables representing the side lengths of the rectangle. Then the area of the rectangle is given by the random variable XY.

We have

$\displaystyle P(XY > 0.5) = \int_{0.5}^1 \int_{0.5/y}^1 dx \, dy \\\\ = \int_{0.5}^1 \left(1-\frac1{2y}\right) \, dy \\\\ = \left(1 - \frac12 \ln(1)\right) - \left(\frac12 - \frac12 \ln\left(\frac12\right)\right) \\\\ = \boxed{\frac{1-\ln(2)}2}$
