The answer is 1, good luck
Answer:
6
Step-by-step explanation:
If each commerical is a minuets and they have six minuets than they can fit six commericals.
Y = -2(x-5)^2 + 4
Note: vertex form is 0, f(x), y, or nothing= a(x-h)^2 + k
The opposite of the x value of the vertex is h
The y value value of the vertex is k.
Find a. Plug in (6,-10)
-10 = a(6-5)^2 + 4
-10 = 1a + 4
-10 = 5a
a = -2

Lol do u really need others to answer this
Congruent triangles have equal corresponding sides and angles.
- The measure of the side lengths are:
,
and 
- The measure of the angles are:
,
and 
The given parameters are:






means that triangles DEF and GHJ are congruent triangles.
So, we have:

This gives

Also, we have:

This gives

Also, we have:

This gives

The following angles are also congruent

This gives

Also, we have:

This gives

The measure of angle J is then calculated using

This gives


Subtract 139 from both sides
