<span>hello :
s² + 5s + 4 = 0
(s+1)(s+4) =0
s+1 =0 or s+4=0
s = -1 or s = -4

Lines a and b are parallel. What is the measure of angle s? Question 4 options: 22 158 44 11 https://screenshots.firefox.com/c21

Temka [501]

If I'm correct 158 and S are supplementary angles, meaning that they both must add up to 180, so to find the answer subtract 158 from 180

180 - 158 = 22
S = 22

If sin(theta) =4/5 and is in quadrant 2, the value of cot(theta

iren [92.7K]

$\sin\theta= \frac{4}{5} 
\\
\\\sin^2\theta+\cos^2\theta=1
\\ \cos\theta=\pm \sqrt{1-\sin^2\theta} =\pm \sqrt{1-( \frac{4}{5})^2 } =\pm \sqrt{1- \frac{16}{25} } =\pm \sqrt{\frac{9}{25} }=\pm \frac{3}{5}}$

$\theta \in II \Rightarrow \cos\theta\ \textless \ 0 \Rightarrow \cos\theta=-\frac{3}{5}$

$\cot\theta= \frac{\cos\theta}{\sin\theta}= \frac{-\frac{3}{5}}{\frac{4}{5}} =- \frac{3}{4}$

Could someone help me please please I have only 2 tries please, please<br>and please explain

Leno4ka [110]

Answer:

Step-by-step explanation:

If the first one is 7 inches long, and 6 inches wide, and the second one is also 7 inches long, but is 6x2 inches wide, then what's the area?

6x2=12

So, Picture Frame 2 = 12 inches wide

Formula for finding area = LxW

L = 7

W = 12

7x12=84

So hence, your answer is 84in²

The area of the second frame is 84in²

Thanks!
