You can find a unit rate when given a rate by dividing the the second number in the rate (if you had 3:4, you would divide 4) by the same number. (in the problem I gave you, you would divide 4 by 4 to get 1 then divide 3 by 4.) Then you would have the unit rate. Sorry if that didn't make any sense.

Answer:

a) line segment

b) point

c) line

Step-by-step explanation:

A line segment is made up of 2 points.

No matter where the lines intersect (doesn't have to be perpendicular), it forms a point.

A line is straight, hence the 3 collinear points.

Answer:

<h2>For the first triangle, <u>x equals 22cm.</u></h2>

Here's how:-

x is the altitude or height of the triangle. To find it, we can use the Pythagoras theorem:-

altitude^{2} + base^{2} = hypotenuse^{2}

The base is 120cm and the hypotenuse is 122cm

Putting this in the equation, we get:-

altitude^{2} + 120^{2} = 122^{2}

altitude^{2} =  122^{2}-  120^{2}

altitude^{2} = 14884 - 14400

altitude^{2} = 484

altitude = \sqrt{484}

<h3>altitude = 22cm</h3><h2><u>So, x = 22cm</u></h2>
