Answer:

84

Step-by-step explanation:

I don't really know how to explain it but I'll try my best

Visualize line AB extending past point A (like it does at point B)

You'll see that 180 ( line AB ) minus 129 is 51

Angle 51 is vertical to  the other angle inside the triangle that is unnamed.

Now you have 2 angles.

180-45-51=84

Look at ΔABC and its 90° rotation.<br>  <br> If AB is 8 inches long, what is the length of A'B' ?

Because the triangle is only rotated, AB and A'B' would be equal. 8 in.

100 notes were altogether

<em><u>Solution:</u></em>

Given that ratio of the number of $2 notes to the number of $5 notes was 4 : 1

number of $2 notes : number of $5 notes = 4 : 1

Let 4x be the number of $ 2 notes

Let 1x be the number of $ 5 notes

Given that total value of notes is $ 260

Therefore,

$ 2 (number of $ 2 notes ) + $ 5(number of $ 5 notes ) = $ 260

$ 2(4x) + $ 5(1x) = $ 260

8x + 5x = 260

13x = 260

x = 20

<em><u>Thus number of notes altogether is given as:</u></em>

4x + 1x = 4(20) + 1(20) = 80 + 20 = 100

Thus 100 notes were altogether
