First, find out x
x+15+2x+15=180
3x+30=180
3x=150
x=50
so the two angels are x+15=65(let's name is ∠5 for convenience), and ∠6= 2x+15=115
notice the two inner lines are marked as congruent, so
∠4=∠5=65
∠1=180-∠4-∠5=180-65-65=50
Name the right bottom angle ∠7, ∠3=∠7 and ∠3+∠7=the exterior angle 100 degree, therefore, ∠3=50
∠2+∠3=∠4, therefore, ∠2=∠4-∠3=65-50=15
∠1=50, ∠2=15, ∠3=50, ∠4=65

Answer:

Step-by-step explanation:
The last one is the answer
A number divides another number of the quotient between the second and the first gives an integer number
<h3>
When a number "divides" another number?</h3>
We say that a number n divides another number m if, when we take the quotient between m and n, the outcome is an integer number.
So we should have that:
m/n = integer number.
This also means that a number only can divide another number if this second number is a multiple of the first one, so if we say that (for example).
m/n = 3
Then:
m = 3*n
So m is a multiple of n, which also means that n divides m.
