ABC is a straight line. Work out the size of the angle marked x

Answer:
x = 57°
Step-by-step explanation:
angles on a straight line add up to 180°. to work out x, we need to subtract 70 and 53 from 180, to get the remaining angle, aka angle x. 180-70=110.
110-53= 57. therefore, x = 57°.
The measure of angle x in the straight line ABC is 57 degrees
An equation is an expression that shows the relationship between two or more numbers and variables.
From the diagram:
x + 53 + 70 = 180° (sum of angles in a straight line).
Hence:
x = 57°
The measure of angle x in the straight line ABC is 57 degrees
