Answer:
7.22
Step-by-step explanation:
3.49+7.50+1.79= 12.78
20.00 -12.78=7.22
to get the slope of any straight line, we can simply use two points off of it, hmmm say let's use here (2,8) and (4,4)

Answer:
16443
Step-by-step explanation:
a = 7676 - b
b = -8767
then:
a = 7676 - (-8767)
a = 7676 + 8767
a = 16443
Check:
16443 -8767 = 7676
Answer: Yes
Step-by-step explanation:

hi <3
so basically, there are a few rules you need to know of and i'll describe those first.
angles in a triangle sum to 180 degrees. AND
angles on a straight line sum to 180 degrees
so, by using the first rule, we can calculate the missing angle within the triangle:
180 - (52 + 90) = 38
now, we can use the second rule to find x
180 - 38 = 142
x = 142 degrees
hope this helps :)
