Slope Formula: $\displaystyle m = \frac{y_2 - y_1}{x_2 - x_1}$

Step-by-step explanation:

Step 1: Define

Identify points

Point (0, 2)

Point (3, -3)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Substitute in points [Slope Formula]: $\displaystyle m = \frac{2 + 3}{0 - 3}$
Simplify: $\displaystyle m = \frac{-5}{3}$

A quadrilateral has three angles that measure 90 100 and 120 which is the measurement of the fourth angle

Lesechka [4]

Answer:

The final angle is 50

Step-by-step explanation:

All quadrilaterals have interior angles that add up to 360. So we can subtract these numbers from 360 to get the final angle.

360 - 90 - 100 - 120 = 50

If the two diagonals are $d$ and $D$ , the are of the rhombus is

$A=\dfrac{dD}{2}$

So, in your case, the area is

$A=\dfrac{15\cdot 35}{2}=262.5$

The other options are wrong because:

option A doens't divide by 2, thus getting twice the area of the rhombus
option B summed the diagonals instead of multiplying them
option D took the difference of the diagonals.
