<2 and <6 are right angles by the definition of perpendicular lines.
Since corresponding angles are congruent, m || n.
11.
In a triangle, the measures of the three angles add to 180 degrees.
If one angle is a right angle, then that angle measures 90 degrees. The other two angle measures plus 90 degrees add to 180 degrees, so the other two angle measures add to 90 degrees. In a right triangle there is a right angle and two other angles that are complementary.
Now look at your problem.
One angle is a right angle.
The other two angles are complementary, so their measures add to 90 deg.
8x + 2 + 9x + 3 = 90
17x + 5 = 90
17x = 85
x = 5
Answer:
$1269.23
Step-by-step explanation:
Since Sarah is paid biweekly (every 2 weeks), and there are 52 weeks in a year...
÷ 
Sarah is being paid 26 weeks out of the year.
Divide 33,000 by 26 (I only list 4 places after the decimal):
÷ 
Round 1269.2307 to the nearest cent (hundredth):
You subtract and find x=10
