Answer:
a
Step-by-step explanation: thats all you need to know
The sum of the interior angles of a triangle = 180 degrees. So, all of the angles on the inside of the triangle will add up to 180.
60 + 40 + ? = 180
100 + ? = 180
? = 80
The missing angle in the triangle is 80 degrees.
Hope this helps!
Answer:
![- 10x - 20y](https://tex.z-dn.net/?f=%20-%2010x%20-%2020y)
Step-by-step explanation:
![- 5(2x + 4y) \\ = - 10x - 20y](https://tex.z-dn.net/?f=%20-%205%282x%20%2B%204y%29%20%5C%5C%20%3D%20%20%20-%2010x%20-%2020y)
If we go based of just looking at the triangles, We can see that the second is enlarged, so all of the sides on the larger triangle will be longer than those on the smaller triangle. This eliminates option G and H.
We can use ratios to solve for the unknown side.
![\frac{9}{13.5} = \frac{15}{x}](https://tex.z-dn.net/?f=%20%5Cfrac%7B9%7D%7B13.5%7D%20%3D%20%5Cfrac%7B15%7D%7Bx%7D%20)
x = 22.5
