Answer: measure angle 2 is 72

Step-by-step explanation: All angles of a triangle add up to 180 so you add 42 and 30 to find measure angle 1 which would be 108 now a horizontal line is 180 is you subtract 108 from 180 and you get 72.

During the regular season, a National Basketball Association team plays 82 games and a National Football League team plays 16 ga
Naddika [18.5K]

Answer:

NFL teams play 16 regular season games each year, NHL and NBA teams play 82, while MLB teams play 162-could invalidate direct comparisons of win percentages alone. As an example, the highest annual team winning percentage is roughly 87% in the NFL but only 61% in MLB and part (but not all) of that difference is undoubtedly tied to the shorter NFL regular season

-x^2+4x-8 <br>axis of symmerty​
V125BC [204]

Answer:

\boxed {\boxed {\sf x=2}}

Step-by-step explanation:

The axis of symmetry can be calculated using the formula:

x=\frac{-b}{2a}

First we must determine a and b from the quadratic: -x^2+4x-8. This is in standard form, with the highest power first in descending order.

Standard form is also: ax^2+bx+c

If we compare this to the quadratic given, we can conclude that:

a= -1 \\b= 4 \\c= -8

Substitute the values for a and b into the formula.

x= \frac{-(4)}{2(-1)}

Multiply in the denominator.

x=\frac {-4}{-2}

Divide.

x=2

This can also be determined from the graph. It is the x-coordinate of the vertex or the maximum/minimum. It divides the quadratic into 2 symmetrical halves.
