Angle RST is a right angle. Angle RSU has a measure of 25°.

Angelina_Jolie [31]

Keywords

complementary angles, right angle

we know that

If two angles are complementary angles, then their sum is equal to a right angle

In this problem

$Angle\ RSU+Angle\ TSU=90\°$ -------> by complementary angles

we have

$Angle\ RSU=25\°$

Substitute and solve for Angle TSU

$Angle\ TSU=90\°-25\°=65\°$

therefore

the answer is the option

$65\°$

use the distance formula to find the distance, to the nearest tenth, between each pair of points (4,5) and (0,2)

Pavlova-9 [17]

Let us use the formula with the point (4,5) and (0,2)

$\begin{gathered} d=\sqrt[]{(x_1-x_2)^2+(y_1-y_2)^2}=\sqrt[]{(4-0)^2+(5-2)^2} \\ =\sqrt[]{16+9}=\sqrt[]{25}=5 \end{gathered}$

I need help finding x

BigorU [14]

Answer:

The answer to your question is x = $\sqrt{50}$ or x = 5 $\sqrt{2}$

Step-by-step explanation:

To solve this problem use the Pythagorean theorem because two right triangles are formed.

c² = a² + b²

c = 10

a = x

b = x Because in a square all the sides measure the same.

10² = x² + x²

- Simplify

100 = 2x²

x² = 100/2

x² = 50

x = $\sqrt{50}$ or x = 5 $\sqrt{2}$
