Answer: 188.81 I think
Step-by-step explanation:
We know that
A linear pair <span>is a pair of adjacent angles formed when two lines intersect.
</span>The two angles of a linear pair are always supplementary , which means their measures add up to 180°
so
ORP and ORN are a linear pair
mORP+ mORN <span>= 180°
</span>80°+ (3x + 10)°=180°
3x=180°-90°
x=90°/3
x=30°
therefore
the answer is the option
A. ORP and ORN are a linear pair
I’m sorry if this is wrong it’s been a while but I’m guessing it’s 9 but if it’s wrong let me know
(7x -7) + (6x +6) = 90
take away the parenthesis: 7x - 7 + 6x + 6 = 90
combine like terms: 13x - 1 = 90
add 1 to both sides: 13x = 91
divide both sides by 13: <span>x = 7.
Now: substitute x = 7 into the angles: the first angle is 42 degrees, the second angle is 48 degrees</span>
Step-by-step explanation:
a -1 2/3
b -1 1/3 they look to be divided into thirds
