12. Find the value of x. (2 points - 1 point for equation, 1 point for answer)
Viktor [21]
Answer: x = 7

-----------------------------------------

Angle STU is 15x. This is the exterior angle on the right side of the triangle
Subtract this from 180 to get angle RTS

angle RTS = 180 - (angle STU)
angle RTS = 180 - 15x

Focus solely on triangle RTS. If needed, erase the portion that extends out toward point U
If we focus on the triangle only, then angle R = angle T since they are the base angles of the isosceles triangle. We know that triangle RST is isosceles since RS = ST is given to us.

Because angle R = angle T, we know 
angle R = 180-15x
angle T = 180-15x
and we also know
angle S = 4x+2
since that's given as well

Add up the three angles and set that sum equal to 180. Then solve for x
R+S+T = 180
(180-15x)+(4x+2)+(180-15x) = 180
(-15x+4x-15x) + (180+2+180) = 180
-26x + 362 = 180
-26x + 362-362 = 180-362
-26x = -182
-26x/(-26) = -182/(-26)
x = 7

For a Chinese New Year celebration, James and Zhou are making a dragon costume similar to the one shown above.
Lilit [14]

Answer:

C. 24 meters

Step-by-step explanation:

Given:

Total length of fabric required for the costume = 56.6 m

Length of fabric Zhou already has = 15 m

Length of fabric James just purchased = 17.6 m

To find how much more length of fabric is required to make the complete costume.

Solution:

<em>Let the length of fabric in meters still required be</em>  = x

<em>The total length can be given as :</em>

⇒ (15+17.6+x)\ m

⇒ (32.6+x)\ m

The total fabric required = 56.6 m

So, the equation to find x will be:

32.6+x=56.6

Subtracting both sides by 32.6

32.6+x-32.6=56.6-32.6

∴ x=24

Thus,<u> 24 meters</u> of fabric is still required to make the costume.
