Answer:
where does the name come from?
Step-by-step explanation:
Supplementary angles must add to 180 degrees. Let x and y be the measure of the two angles.
y= 6x+5
x+y=180
Substitute y
x+6x+5=180
7x+5=180
7x=175
x=25
Plug the value of x in
25+y=180
y=155
Final answer: 155 degrees
Answer:
Step-by-step explanation:
a^2+6^2 = 23^2
a^2 = 23^2 - 6^2
a^2 = 529 - 36
a^2 = 493
a = √493
a = 22,20
Pedro made mistake in step 3.
He supposed to plug in y = 12 into the y in the equation to solve for x
Should be:
-14x - 2(2)=24
-14x - 4 = 24
-14x = 28
x = -2
