Answer:

16 over 18 or simply 8/9

Step-by-step explanation:

7/18 + 9/18, since the denominators are same, you just add the numerators and you get 16/18, which simplifies to 8/9

Angles a and b in both angles sets are ?

Alex17521 [72]

Answer:

1) b = 60°

2) a = 90°, b = 90°

Step-by-step explanation:

1) Angles on a straight line add to 180° so 180 - 120 is 60°

2) The two lines are perpendicular (meet at right angles) so both angles are 90°

Answer:

Distance = 5 units

Step-by-step explanation:

The given problem asks us to determine the distance between two points, (1, 5) and (5, 2).

<h2>Solution:</h2>

In order to find the distance between two points, we can use the following distance formula:

$\displaystyle\mathsf{Distance\:(D)= \sqrt{(x_2\:-x_1)^2\:+\:(y_2\:-y_1)^2}}$

Let (x₁, y₁) = (1, 5)

(x₂, y₂) = (5, 2)

Step 1: Substitute points into the formula:

$\displaystyle\mathsf{Distance\:(D)= \sqrt{(x_2\:-x_1)^2\:+\:(y_2\:-y_1)^2}}$

$\displaystyle\mathsf{Distance\:(D)= \sqrt{(5\:-1)^2\:+\:(2\:-5)^2}}$

Step 2: Subtract the integers in each of the parenthesis under the radical:

$\displaystyle\mathsf{Distance\:(D)= \sqrt{(4)^2\:+\:(-3)^2}}$

Step 3: Evaluate the powers (exponents):

$\displaystyle\mathsf{Distance\:(D)= \sqrt{16\:+\:9}}$

Step 4: Add 16 and 9:

$\displaystyle\mathsf{Distance\:(D)= \sqrt{25}}$

Step 5: Take the square root of 25:

⇒ Distance (D) = 5 units.

<h2>Final Answer:</h2>

Therefore, the distance between points (1, 5) and (5, 2) is <u>5 units</u>.
