You have to measure the angles and side on your own because you have to use a protractor/ruler.
But for classification:
1. acute triangle and 3 acute angles
2. right triangle and 1 right angle
3. isosceles triangle and 2 equal sides
4. equilateral triangle and 3 equal sides
Answer:

Step-by-step explanation:
From the differential equation given:

The equation above can be re-written as:


Let assume that if function M(x,y) and N(x,y) are continuous and have continuous first-order partial derivatives.
Then;
M(x,y) dx + N (x,y)dy = 0; this is exact in R if and only if:

relating with equation M(x,y)dx + N(x,y) dy = 0
Then;

So;


Let's Integrate
with respect to x
Then;


Now, we will have to differentiate the above equation with respect to y and set
; we have:

Hence, 
Finally; the general solution to the equation is:

#7:
<span>Subtract </span>y<span> from both sides:
</span>-4x=6-y
Divide both sides by -4:
Answer:
x= -6-y/4
#7 part 2:
Add <span>y</span><span> to both sides:
</span>-5x=21+y
Divide both sides by -5:
Answer: x=-21+y/5

Answer:
= 3f + 8
Step-by-step explanation:
Given that:
= 2/3[3f+12]+f
By simplifying:
2/3 will be multiplied inside the bracket as follows:
= 2/3*3f + 2/3*12 + f
By cancelling the terms with each other we get:
= 2f + 24/3 + f
By simplifying the fraction we get:
= 2f + 8 + f
Adding like terms
= 3f + 8
This is the simplified expression.
i hope it will help you!
