Answer:

96 degrees

Step-by-step explanation:

you have two angles that each measure 42 degrees, giving you 84 degrees combined

there are 180 degrees in a triangle, therefore the vertex angle is equal to 180 minus 84, or 96 degrees

check:

42 + 42 + 96 = 180

180 = 180

A DVD player is regularly priced at 79.95 and is on sale for 30% off. What is the discount?
evablogger [386]

Answer:

$2.40 or $77.55

Step-by-step explanation:

I don't know if you are asking for how much off or what, so I'm doing both

First, we have to find how much we have to take off or what is 30% of 79.95 so our equation is:

79.95 x 0.03 = 2.40

So 30% of 79.95 is $2.40

To find how much our new price sale is, we have to take that $2.40 off so our equation is:

79.95 - 2.4 = 77.55

So our discount price is $77.55

hope this helps:)

Which value must be added to the expression x^2 +16x to make it perfect-square trinomial?
Semmy [17]
X^2 + 16x + ?
a^2 + 2ab + b
(a + b)^2 which is a perfect square.

To find b to determine the last value, you divide 16x by 2x.
so:
b = 8
the last value would be 8^2 which is 64.

Hence answer is C - 64
