Step-by-step explanation:
Here the angle, a is 60°, Opposite is 20 and adjacent is x.
Therefore we have,
Making x the subject gives us
Part B
Value of x to the nearest tenth
Answer:
Linear pair
Step-by-step explanation:
<1 and <2 lie on a straight line.
Angles that lie on a straight line are considered as linear pair angles.
Linear pair angles sum up to 180°, which is the measure of a straight line angle.
Hey there!
For all this, we'll start with defining any variable as "a number", as we're using words.

b) Two times the sum of x and y.
c) Three subtracted from the sum of a number and five.
Hopefully this helps!
