Use the double angle function sin2x = 2sinxcosx.

2sinxcosx + sinx = 0

For the first part of the problem, consider the solutions on the interval where sinx = 0

x = 0, pi

Now consider the solutions where sinx does NOT equal zero.

2sinxcosx + sinx = 0

2sinxcosx = - sinx

2cosx = - 1

cosx = - 1/2

x = 2pi/3, 4pi/3

Answer:

68 degrees

Step-by-step explanation:

This triangle is an isosceles triangle which means that two sides have equal lengths and when two sides have equal lengths that means that two angles are the same. so you add 56 and 56 together and you get a sum of 112. all triangles add up to a degree of 180, so you therefore subtract 112 from 180 which gives you an answer of 68 degrees , therefore x is 68

Multiply and simplify.
ankoles [38]

Answer:

10  g^4  h^9

Step-by-step explanation:

-5gh^4 * (-2g^3 h^5)

Rewriting

-5*-2   g*g^3   h^4*h^5

When the bases are the same, we add the exponents (x^a * x^b = x^ (a+b)

There is an implied 1  if there is no exponent

-5*-2   g^1*g^3   h^4*h^5

10  * g^(1+3)  h^(4+5)

10  g^4  h^9
