Determine the number of possible triangles, abc, that can be formed given a = 30°, a = 4, and b = 10.
0
1
2

Option A is the correct answer

Step-by-step explanation:

We have sine formula

Here A = 30°, a = 4, and b = 10

Value of sine cannot be greater than 1.

So these combination is not possible.

We cannot form a single triangle with these sides and angle.

Option A is the correct answer

the answer is b.)

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice

p.s.   i'll be on vacation from friday, dec 22 to jan 2, 2019. have a great new year!
