4×11+1=45
A+B+C=180 60+75+C=180 180_130=c c=45
That's OK, but you have not said which variable you want to solve it for.
<u>To solve for 'x':</u>
<span>c + ax = dx
Subtract c from each side: ax = dx - c
Subtract dx from each side: ax - dx = -c
Factor the left side: x (a - d) = -c
Divide each side by (a - d) : x = -c / (a - d) or <u>x = c / (d - a)</u> .

Subtract ax from each side and factor: <u>c = x (d - a) </u>

Subtract 'c' from each side: ax = dx - c
Divide each side by 'x': <u>a = d - c/x </u>.

Answer:
They're congruent if they have the exact same sides and the exact same angles. So from what i can see, yes they are congruent.
Step-by-step explanation:
The two triangles will be similar (same shape, and each side of one triangle the same multiple of the corresponding side of the other triangle), but not necessarily the same size.
The key word here is "similar;" be sure you understand what that means in trig.
Answer:
Step-by-step explanation:
For this exercise it is important to remember the multiplication of signs:
In this case, given the following expression:
You can idenfity that both factors are negative. Then, the product (The result of the multiplication) will be positive.
Then, in order to get the product, you need to multiply the numerator of the fraction by -8. So, you get:
You can notice that the numerator and the denominator of the fraction obtained cannot be divided by the same number; therefore, the fraction cannot be simplified.
