Answer:

The correct answer is option B. 44°

Step-by-step explanation:

From the figure we can see a circle, and an angle subtended.

The angle from an arc subtended n the other arc of a circle is half the angle made by the arc in center.

<u>To find the measure of m<ABC</u>

Here the central angle of arc AC is 88°,

<ABC is half the central angle made by arc AC

Therefore m<ABC = 88/2 = 44°

The correct answer is option B. 44°

A soldier started patrolling around his camp at 22 30 . His patrol lasted 3 hours and 20 minutes .What time did his patrol end

baherus [9]

Answer:01 50 Hrs

Step-by-step explanation:

If the soldier started patrol at 2230 hrs and his petrol lasted for 3 hours and 20 minutes, that means he was on patrol for that time.

The time he finished was therefore:

= 2230 + 320

= 2550

At 24 you begin at 0:00am so:

= 2550 - 2400

= 150

Patrol ended at 0150 hrs

Answer:

There are two possible solutions:

Clockwise rotation

$P'(x,y) = (-10,5)$

Counterclockwise rotation

$P'(x,y) = (10, -5)$

Step-by-step explanation:

There are two possible answers: (i) Clockwise rotation, (ii) Counterclockwise rotation. Vectorially speaking, rotation of point of rotation of a point about another point of reference is defined by:

$P'(x,y) = O(x,y) + r_{OP}\cdot (\cos (\theta_{OP}\pm \theta'),\sin (\theta_{OP}\pm \theta'))$ (1)

Where:

$O(x,y)$ - Point of reference.

$r_{OP}$ - Length of the segment OP.

$\theta_{OP}$ - Direction of segment OP, measured in sexagesimal degrees.

$\theta '$ - Angle of rotation, measured in sexagesimal degrees.

Please notice that clockiwise rotation occurs when $\theta = \theta_{OP}-\theta'$ and counterclockwise rotation when $\theta = \theta_{OP}+\theta'$ . In addition, we define length and direction of the segment below:

$r_{OP} = \sqrt{(x_{P}-x_{O})^{2}+(y_{P}-y_{O})^{2}}$ (1)

$\theta_{OP} = \tan^{-1} \frac{y_{P}-y_{O}}{x_{P}-x_{O}}$

If we know that $x_{O} = y_{O} = 0$ , $x_{P} = 5$ , $y_{P} = 10$ and $\theta' = 270^{\circ}$ , then the coordinates of the first car after rotation is:
