Answer:

32

Step-by-step explanation:

Because two of the sides are equal it means the angles that are left are equal. The sum of the angles in a triangle is 180. To get the answer we subtract 116 from 180. Which gives us 64. Since the remaining two angles are equal 64 is then divided by 2 to get 32.

Answer:

32

Step-by-step explanation:

every triangle adds up to 180, so 180-119=64

then you divide because there are two 'b's 64/2= 32

Determine the x-intercept for 3x + 2y = 14.

spin [16.1K]

First isolate y

3x + 2y = 14

-3x -3x

2y = -3x + 14

y = -3/2x + 14/2

y = -3/2x + 7

X-intercept is found when y = 0

0 = -3/2x + 7

-7 = -3/2x

x = 14/3

x-in. = (14/3,0)

If f(x)=ln(sin(2x)), f''(π/4) is equal to

Licemer1 [7]

Use the chain rule to compute the second derivative:

$f(x)=\ln(\sin(2x))$

The first derivative is

$f'(x)=(\ln(\sin(2x)))'=\dfrac{(\sin(2x))'}{\sin(2x)}=\dfrac{\cos(2x)(2x)'}{\sin(2x)}=\dfrac{2\cos(2x)}{\sin(2x)}$

$f'(x)=2\cot(2x)$

Then the second derivative is

$f''(x)=(2\cot(2x))'=-2\csc^2(2x)(2x)'$

$f''(x)=-4\csc^2(2x)$

Then plug in π/4 for <em>x</em> :

$f''\left(\dfrac\pi4\right)=-4\csc^2\left(\dfrac{2\pi}4\right)=-4$
