Sorry again but i'm having trouble on this one

Lisa [10]

Answer:

m∠PNO = 60°

m∠O = 33°

Step-by-step explanation:

∡NPO is 87° because it's a vertical angle with the 87° angle

3) ∡PNO is supplementary to the 120° angle (they must add to 180°)

4) m∠O = 180 - (60 + 87) = 33

What is the sum of the arithmetic series? ∑[i=1,15,Fn=5i-1]

Helen [10]

$\bf \sum\limits_{i=1}^{15}\ 5i-1\implies 5\sum\limits_{i=1}^{15}\ i-\sum\limits_{i=1}^{15}\ 1\implies 5\left[ \cfrac{15(15+1)}{2} \right]-(15\cdot 1)
\\\\\\
5\cdot (15\cdot 8)-15\implies 585$

Write an equation in point-slope form for the line through the given point that has the given slope (-2,-7);m=-3/2

love history [14]

For this case we have that the point-slope equation of a line is given by:

$(y-y_ {0}) = m (x-x_ {0})$

Where:

m: It's the slope

$(x_ {0}, y_ {0}):$ It is a point

We have as data that:

$(x_ {0}, y_ {0}): (- 2, -7)\\m = - \frac {3} {2}$

We replace:

$(y - (- 7)) = - \frac {3} {2} (x - (- 2))\\(y + 7) = - \frac {3} {2} (x + 2)$

Answer: $(y + 7) = - \frac {3} {2} (x + 2)$
