Find x and round to nearest tenth

Lesechka [4]

Answer:

x=13.5

Step-by-step explanation:

Using the formula:

Sin theta=opposite/hypotenuse

Where theta=57 degrees

opposite =10.8

hypotenuse =x

Sin57=10.8/x

Xsin57=10.8

x=10.8/sin57

x=10.8/0.8

x=13.5

Prove that the following four points will form a rectangle when connected in order

Lemur [1.5K]

Answer:

Step-by-step explanation:

If the diagonals of the rectangle are congruent,

AC = BD

By using formula to calculate the distance between two points,

Distance between two points = $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

Distance between A(0, -3) and C(2, 8),

AC = $\sqrt{(8+3)^2+(2-0)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Similarly, distance between two points B(-4, 0) and D(6, 5),

BD = $\sqrt{(5-0)^2+(6+4)^2}$

= $\sqrt{125}$

= $5\sqrt{5}$

Therefore, both the diagonals are congruent.

Hence, given quadrilateral ABCD is a rectangle.
