Answer:

x= -4, -3, 3

Step-by-step explanation:

You must factor this equation.

Once you factor, you get (x+4)(x-3)(x+3)

What are the lengths of the legs of a right triangle in which one acute angle measures 19o and the hypotenuse is 15 units long?

WITCHER [35]

$x,y-\ lengths\ of\ legs\\\\sin19^\circ=\frac{x}{15}\\\\ sin19^\circ*15=x\\\\0,32*15=x\\\\x=4,8\\\\
y^2+(4,8)^2=15^2\\\\y^2=225-23,04\\\\ y^2=201,96\\\\y=14,2\\\\Legs\ are\ equalt\ to:\ 4,8 \ and\ 14,2.$

Sin(-180° + θ) = ________

Svet_ta [14]

Answer:

$\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)$

Step-by-step explanation:

We need to find the value of $\sin(-180^o+ \theta)$

So let's apply formula

$\sin\left(A+B\right)=\sin\left(A\right)\cos\left(B\right)+\sin\left(B\right)\cos\left(A\right)$

$\sin\left(-180^o+\theta\right)=\sin\left(-180^o\right)\cos\left(\theta\right)+\sin\left(\theta\right)\cos\left(-180^o\right)$

$\sin\left(-180^o+\theta\right)=0\cdot\cos\left(\theta\right)+\sin\left(\theta\right)\cdot\left(-1\right)$

$\sin\left(-180^o+\theta\right)=0-\sin\left(\theta\right)$

$\sin\left(-180^o+\theta\right)=-\sin\left(\theta\right)$
