There are a few ways to answer. The simplest of which is to simply say "angle 1" which is written as m \angle 1 or you can say "angle ELS" or "angle SLE" written as m \angle ELS and m \angle SLE respectively. All three of these angles represent the same idea.

It might help if you used a different color marker to help see what's going on. In figure 1 (see attached image), I've marked angle ALS in green. Then if you take out angle 2 from the angle ALS, then you'll be left over with just angle 1. Angle 2 is marked in blue and angle 1 is marked in red. This is shown in figure 2.

Measure of angle 1.
Angle ALS consists of angle 1 and 2. When you take the angle 2 away, subtract it, it ends with angle one.

Determine whether or not 630 is a triangular number. start with the formula t n = n ( n + 1 ) 2 and then use the quadratic formu
ziro4ka [17]
Triangular sequence = n(n + 1)/2

If 630 is a triangular number, then:

n(n + 1)/2  = 630

Then n should be a positive whole number if 630 is a triangular number.

n(n + 1)/2  = 630

n(n + 1)  = 2*630

n(n + 1)  = 1260

n² + n = 1260

n² + n - 1260 = 0

By trial an error note that 1260 = 35 * 36

n² + n - 1260 = 0

Replace n with 36n - 35n

n² + 36n - 35n - 1260 = 0

n(n + 36) - 35(n + 36) = 0

(n + 36)(n - 35) = 0

n + 36 = 0   or   n - 35 = 0

n = 0 - 36,   or  n = 0 + 35

n = -36, or 35

n can not be negative. 

n = 35 is valid.

Since n is a positive whole number, that means 630 is a triangular number.

So the answer is True.

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
