Multiply the two brackets together

(3-21)(3+21)

(3)(3)(3)(+21)(-21)(3)(-21*21)

9+63-63-441

- 441 because whenever multiplying a - negative number and a + positive number = - negative number

9-441

= -432

Answer: -432

What is the lim (1-cos theta)/(2sin^2 theta) as theta approahes 0?

Sergio039 [100]

$\displaystyle
\lim_{\theta\to 0}\dfrac{1-\cos \theta}{2\sin ^2\theta}=\\\\
\lim_{\theta\to 0}\dfrac{(1-\cos \theta)(1+\cos \theta)}{2\sin ^2\theta(1+\cos \theta)}=\\\\
\lim_{\theta\to 0}\dfrac{1-\cos^2 \theta}{2\sin ^2\theta+2\sin^2 \theta\cos \theta}=\\\\
\lim_{\theta\to 0}\dfrac{\sin^2 \theta}{2\sin ^2\theta+2\sin^2 \theta\cos \theta}=\\\\
\lim_{\theta\to 0}\dfrac{1}{2+2\cos \theta}=\\\\
\dfrac{1}{2+2\cdot1}=\\\\
\dfrac{1}{4}

Can the two triangles be proven congruent through SSS or HL? answers: A) No, the triangles are congruent only through ASA. B) No

sleet_krkn [62]

Answer:

Step-by-step explanation:

HL means Hypotenuse-Leg and applies only to right triangles. These triangles are not right triangles since they have an obtuse angle, so HL is out.

To use SSS, you need all three sides of one triangle to be congruent to the three sides of another triangle. Here we do not have that.

There isn't enough info to use ASA either.

Answer: B)
