Is it ever possible that sin (A+B)=⁡ (A+B)= sin⁡ A+sin⁡ B?

Cloud [144]

Answer:

It will always be the case when A and B are opposites

Step-by-step explanation:

sin(x) = -sin(-x) so ...

sin(A -A) = (A -A) = sin(A) -sin(A) = 0

That is, the given expression is true when B=-A.

FGH and HGJ form a linear pair. Find the measurement of the anglesif FGH=11x and HGJ+(6x-7)

horrorfan [7]

The angles are 121 and 59 degrees, respectively

<h3>How to determine the angles?</h3>

The given parameters are:

FGH = 11x

HGJ = 6x - 7

Linear pair angles add up to 180.

So, we have:

11x + 6x - 7 = 180

Evaluate the like terms

17x = 187

Divide both sides by 17

x = 11

Substitute x = 11 in FGH = 11x and HGJ = 6x - 7

FGH = 11 * 11=121

HGJ = 6 * 11 - 7 = 59

Hence, the angles are 121 and 59 degrees, respectively
