Answer:Use the quadratic formula to find the solutions. Substitute the values a=1 , b=−4 , and c=−38 into the quadratic formula and solve for x .

step by step:

Move 29 29 to the left side of the equation by subtracting it from both sides. Subtract 29 29 from −9 - 9 .

3rd question, I’m sorry guys but I was sick that’s why I didn’t attend school and the teacher said if I didn’t submit it by 5 ho
aniked [119]

Answer:

21.  ΔUYZ <u>Obtuse</u>

22. ΔBCD <u>Right or Rectangle</u>

23. ΔADB <u>Acute</u>

24. ΔUXZ <u>Acute</u>

25. ΔUWZ <u>Right or Rectangle</u>

26. ΔUXY <u>Equiangular and acute</u>

Step-by-step explanation:

We need to classify each triangle by its angles.

Acute: They have 3 acute angles (less than 90 degrees).

Rectangle: The inner angle A is straight (90 degrees) and the other 2 angles are sharp. The sides that form the right angle are called legs (c and b), the other side hypotenuse.

Obtuse: The inner angle A is obtuse (more than 90 degrees). The other 2 angles are acute.

ΔUYZ Obtuse  The inner angle Y is obtuse (more than 90°).

ΔBCD Right or Rectangle The inner angle C is straight (90°).

ΔADB Acute It has 3 acute angles (less than 90°).

ΔUXZ Acute  It has 3 acute angles (less than 90°).

ΔUWZ Right or Rectangle The inner angle W is straight (90°).

ΔUXY Equiangular and acute Which means all the inner angles are equal (60°).

Find all solutions and solutions in interval[0,2pi)
frutty [35]
\bf sin(2\theta)=2sin(\theta)cos(\theta)\\\\&#10;-------------------------------\\\\&#10;sin(2x)-\sqrt{3}cos(x)=0\implies 2sin(x)cos(x)-cos(x)\sqrt{3}=0&#10;\\\\\\&#10;\stackrel{\stackrel{common}{factor}}{cos(x)}[2sin(x)-\sqrt{3}]=0\\\\&#10;-------------------------------\\\\

\bf cos(x)=0\implies \measuredangle x=&#10;\begin{cases}&#10;\frac{\pi }{2}\\\\&#10;\frac{3\pi }{2}&#10;\end{cases}\\\\&#10;-------------------------------\\\\&#10;2sin(x)-\sqrt{3}=0\implies 2sin(x)=\sqrt{3}\implies sin(x)=\cfrac{\sqrt{3}}{2}&#10;\\\\\\&#10;\measuredangle x=&#10;\begin{cases}&#10;\frac{\pi }{3}\\\\ \frac{2\pi }{3}&#10;\end{cases}

Prove that the two circles shown below are similar. ​
Setler [38]

Answer:

The scale factor is \frac{R_{A}}{R_{C}}=\frac{5}{2}

<u>We can say that both circles are similar.</u>

Step-by-step explanation:

If we move the little circle to the center of the bigger circle, so the <u>translate vector will be (3,5).</u>

Now we realize that the bigger circle is just a dilation of the smaller circle, the<u> scale factor is:</u>

R_{A}=5

R_{C}=2

\frac{R_{A}}{R_{C}}=\frac{5}{2}

Therefore, <u>we can say that both circles are similiar.</u>

<u />

I hope it helps you!
