Answer:
you can not make 2 tringles and get a bigger tringle
Step-by-step explanation:
it makes a dimond shape
<u>Using Cosine Rule:</u>
5² = 7² + 6² - 2(7)(6) cos(F)
25 = 85 - 84cos(F)
84 cos(F) = 60
cos(F) = 5/7
F = cos⁻¹(5/7)
F = 44°
Answer: 44°
Sorry i dont speak this language
In this question, they gave you the system of equations. You just need to use the two of them.
We want to find the m or the number of the multiple-choice questions. So we need to turn our last equation in the form of 'm's by translating the 'f's into 'm's.


If we know the m form of f, we can convert the second equation and find the answer:

Plug in the m value of f:

Distribute the 5:

Subtract -75 from both sides:

Combine like terms:

Divide both sides by -2:

So, we learned that the number of the multiple-choice questions is 12.
Answer:
12x + 27
Step-by-step explanation:
3(4x+9) = 12x + 27
