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>

RS bisects QRT, mangleQRS = (3x + 8), and mangleSRT = (5x − 4).
Leya [2.2K]

Bisect typically means half but since we aren't given angle at the start so we can just have to solve for x.

(3x + 8) = (5x - 4)

3x = 5x - 12

-2x = -12

x = 6

Best of Luck!

The ratio of the mass of an ant to the mass it can carry 1:50
slavikrds [6]

The ratio 1:50 means that an ant can carry an object heavy 50 times its mass.

So, if the mass of the ant is 0.4 grams, it can carry at most 50 times that mass, i.e. 50x0.4 = 20 grams

In order to answer the second question, you need to consider your mass and multiply it by 50: if you were as strong as an ant, you could lift that weight!
