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

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

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

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

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

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

What two theorems are being used ?

leva [86]

Answer:

Angle-Angle-Angle(AAA)
Side-Angle-side(SAS)

Step-by-step explanation:

Let's see what is similar in both triangles

<A=<F
<B=<E
<C=<D

So Angle-Angle-Angle similarly theorem verified

AB=ED
FD=BC
BC=EF

So Side-Angle-side or Side-Side-Side similarity theorem verified

I am thinking of a number.

Step2247 [10]

Step-by-step explanation:

Let the number Noah is thinking of be x,

=> x - 19 * 4 = 16

=> x - 19 = 16/4

=> x = 16/4 + 19

=> x = 4 + 19

=> x = 23

PERSEVERE Find the values of x and y,

Vlad [161]

y² = 8y - 15 (alternate angles are equal)

y² - 8y + 15 = 0

(y - 5)(y - 3) = 0

y = 5 or 3

x + 8y - 15 = 180 (angles in a straight line add up to 180)

when y = 5

x + 40 - 15 = 180

x = 155°

when y = 3

x + 24 - 15 = 180

x = 171°
