Find the indicated angle or side. Give an exact answer.<br> Find the measure of angle A in degrees.
Anna35 [415]

Step-by-step explanation:

law of cosine :

c² = a² + b² - 2ab×cos(C)

with c being the side opposite of C.

so, in our case

3² = 3² + 3²×3 - 2×3×3×sqrt(3)×cos(A)

0 = 3²×3 - 18×sqrt(3)×cos(A)

27 = 18×sqrt(3)×cos(A)

cos(A) = 27/(18×sqrt(3)) = 3/(2×sqrt(3)) =

= 0.866025404...

A = 30°

FYI : since it is an isoceles triangle, C = A = 30°.

and therefore B = 180 - 30 - 30 = 120°.

as the sum of all angles in a triangle is always 180°.

Consider the function FX equals -2/3 X -24 which conclusions can be drawn about F negative 1X select two options a F negative 1X
omeli [17]

The conclusions that can be drawn about f–1(x) are:

  • f^-^1(x) has an x-intercept of (-36, 0)
  • f^-^1(x) has a range of all real numbers.

<h3>Calculations and Parameters:</h3>

Given:

f(x) = \frac{-2}{3}x - 24

f(x) + 24 = \frac{-2}{3}x

To find x, we would multiply both sides by -2/3

= x= \frac{-3}{2} (f(x) + 24)

f^-^1(x) = -\frac{3}{2} (0) - 36

f^-^1(x) = -36

Therefore, f^-^1(x)  has an x-intercept of (-36, 0)

Furthermore, f^-^1(x) has a range of all real numbers.

What value of x is in the solution set of 9(2x + 1) &lt; 9x - 18? <br> -4<br> -3<br> -2<br> -1
Anastaziya [24]

Answer:

The only possible answer that is correct is the first one, x = -4.

Step-by-step explanation:

Simplify the given inequality as much as possible, and then substitute each of the given x values one by one to determine which is in the solution set.

9(2x + 1) < 9x - 18 becomes 18x + 9 < 9x - 18, which, if reduced by dividing all four terms by 9, becomes 2x + 1 < x - 2.

Simplifying further, we get x < - 3.  The only possible answer that is correct is the first one, x = -4.  -4 < -3 is true.
