Answer:

x = 70

Step-by-step explanation:

The measure arc AC is twice as angle B

The center angle that sees arc is equal to the arc it sees

<B = 2x - 65 so the measure of arc AC is 4x - 130 since this is gonna complete 3x to 360°

4x - 130 + 3x = 360°

7x = 490

x = 70

Westkost [7]

Answer:

The triangle will translate along the arrow and reach the head of the arrow.

Step-by-step explanation:

Translation is a category of motion in which one body moves along towards a particular direction and reaches a particular point.

In translation, the rotational motion is not present. Also, the translational motion is a one dimensional motion.

In the given figure, the triangle is present at the tail of the arrow.

The arrow depicts the direction of the translational motion.

So, the triangle will reach the end of the arrow as shown in the picture present in the attachment.
