Angle α lies in quadrant II , and tan α = <img src="https://tex.z-dn.net/?f=-%5Cfrac%7B12%7D%7B5%7D" id="TexFormula1" title="-\f

Hunter-Best [27]

Since $\alpha$ lies in quadrant II and $\beta$ lies in quadrant IV, we expect $\sin\alpha>0$ , $\cos\alpha$ , and $\sin\beta$ .

Recall the Pythagorean identities,

$\sin^2x+\cos^2x=1\iff1+\cot^2x=\csc^2x\iff\tan^2x+1=\sec^2x$

It follows that

$\sec\alpha=\dfrac1{\cos\alpha}=-\sqrt{\tan^2\alpha+1}=-\dfrac{13}5\implies\cos\alpha=-\dfrac5{13}$

$\sin\alpha=\sqrt{1-\cos^2\alpha}=\dfrac{12}{13}$

$\sin\beta=-\sqrt{1-\cos^2\beta}=-\dfrac45$

Recall the angle sum identity for sine:

$\sin(\alpha+\beta)=\sin\alpha\cos\beta+\sin\beta\cos\alpha$

So we have

$\sin(\alpha+\beta)=\dfrac{12}{13}\dfrac35+\left(-\dfrac45\right)\left(-\dfrac5{13}\right)=\boxed{\dfrac{56}{65}}$

If m angle ABC=180. What is the degree measure of angle ADC

Damm [24]

Answer:

if ∠ABC = 180°,

then, 2x∠ADC = ∠ABC ( angles subtended by an arc at the center is double the angle subtended it at any point on the remaining part if the circle)

{ please read the theorem carefully as i know u wont be able to understand it at first try :) }

therefore ∠ADC = 90°

Tyreek and his 4 friends equally split 3cups of juice. How much juice does each person get?

lyudmila [28]

Answer:

$\frac{3}{5}$ or 0.6 of a cup of juice

Step-by-step explanation:

Divide 3 by 5:

3/5

= 0.6

So, each person would get $\frac{3}{5}$ or 0.6 of a cup of juice.
