In ΔMNO, m = 780 inches, o = 760 inches and ∠O=164°. Find all possible values of ∠M, to the nearest degree.
Mademuasel [1]

Answer:

So the answer is both

180 and 328 (but it may or may not show you "not possible, if so, then you got it right)

Step-by-step explanation:

SinA/a= SinB/b

1. SinM/780 = Sin164/760

2. 780sin164/760 = 0.2828909704

3. M = sin^-1 (0.2828909704)= 16.4328229 or 16

Check for possibility

180-16= 164

164 + 16= 180 (not possible)

164 + 164= 328 (not possible)

What is equivalent to 2x^2+9x+9
melamori03 [73]

(2x + 3) • (x + 3)

2x • x = 2x^2

2x • 3 = 6x

3 • x = 3x

3 • 3 = 9

6x and 3x combine to get 9x, which when all written out is equal to your original trinomial.

How can I tell if something is linear or nonlinear?
Anni [7]

Answer:

When something is linear it will meet the criteria, on a graph it will be a straight line, it won't have any curves in it.

When something is nonlinear it doesn't fit the criteria, on a graph it will be curved, never straight

Hope this helps ;)
