Answer:
x = 55
Step-by-step explanation:
a triangle's angles must equal when added up to 180.
so
76 + 49 + x = 180
combine terms
125 + x = 180
x = 55
The slope is -10, I used a graph for this.
You have -4,-3,-2, that is a 3 out of a total of 21 points or numbers on the number line. 3/21 is reduces to 1/7.
3 goes into 21 , 7 times. That is why it reduces to 1/7.
