Answer:
Answer:
The measure of angle x is 50 degrees
Step-by-step explanation:
we know that
x+y=90x+y=90 ----> equation A
x=2y-30x=2y−30 ----> equation B
solve the system by substitution
substitute equation B in equation A
(2y-30)+y=90(2y−30)+y=90
solve for y
3y=90+303y=90+30
3y=1203y=120
y=40^oy=40
o
Find the measure of angle x
x=2(40)-30=50^ox=2(40)−30=50
o
therefore
The measure of angle x is 50 degrees
Answer:
The central idea is what the text is mainly about. It is not the topic of the text. The central idea can most often be stated in one sentence. Think of it as the thesis in an essay.
