Angles and Lines

We must recall:

The image shows a triangle and the extension of its base to form two linear angles.

Note from the triangle, angle R is what it takes to get to 180°:

From the line SQ, angle R what it takes to get to 180°. Thus:

Equating:

Subtracting 180 and simplifying:

Dividing by 19:

x=3

42.4

step-by-step explanation:

convert to decimal

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
