<2 and <6 are right angles by the definition of perpendicular lines.
Since corresponding angles are congruent, m || n.

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: f(x)= 8
Step-by-step explanation:
First you would plug in F(3) into the equation
replace the x with a three
f(x)=2(3)+2
then multiply the 2 and 3 because when you see a number next to another number in parenthesis you multiply them
f(x)=6+2
Then lastly you would add the result of your multiplied numbers with the two which gives you f(x)=8.
<u>f(x)=8</u>
One ticket = $23.78
Michael bought 4 tickets. We need to find the total cost of the tickets.
We use multiplication to solve this problem.
4 * 23.78 = 95.12
So, the total cost is $95.12.
Answer:
1
Step-by-step explanation:
These appear to be right triangles? Otherwise you would have to use the special triangle formulas. If they are right triangles, use the pythagorean theorem.
