Answer:
10 degrees
Step-by-step explanation:
1.) every triangle has angles that add up to 180 degrees
2.) a right triangle has a right angle and two acute angles
3.) right=90 degrees; acute=<90 degrees
4.) 90+80=170
5.) 180-170=10
Answer:
An even function is:
f(x) = 7
Step-by-step explanation:
An even function accomplish the following condition:
f(x)=f(-x) (1)
Applying (1), we have:
- f(x)= (x-1)^2
f(-x)
(-x-1)^2 - f(x)= 8x
f(-x)
-8x - f(x)= x^2 -x
f(-x)
(-x)^2 +x
The last one is even.
To rearrange the equation given, we need to take note the rules in adding, subtracting, multiplying and dividing terms. We rearrange the equation as follows:
<span>((a+b/c)(d-e)=f) 1/(d-e)
</span>(a+b/c = f/(d-e))c
a+b = fc/(d-e)
a = [fc/(d-e)] - b
Hope this answers the question.
