Sin(a+/-b)=sin(a)cos(b)+/-cos(a)sin(b)
sin(17+26)=sin(17)cos(26)+cos(17)sin(26)
Answer: sin(43)
Answer:
6x^2+ 19x+8
Step-by-step explanation:
(3x+8)(2x+1) use foil method which gives you,
6x^2+16x+3x+8 then combine like terms which gives you,
6x^2+ 19x+8.
Answer:
<h2>C</h2>
Step-by-step explanation:
using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get
8^2+23^2=c^2
then, using our big math brains, we get 64+529=c^2
adding together the numbers, we end up with 593
just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C
Answer:
x = 12
Step-by-step explanation:
42 + 4x = 90 ( as it is right angle)
transpose to find x
4x = 90 - 42
4x = 48
x = 48/4
x = 12
No, it's not possible for the sides of a triangle to have those lengths.
According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.

This inequality satisfies the triangle inequality theorem.

This also satisfies the theorem.

Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.
