(2,0)
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 :)
Answer:
x = 3.5
Step-by-step explanation:
First, we'll expand the parenthesis by multiplying 2x and -9 with 5:
Let's just simplify -45 + 3:
Now we can add 42 to both sides:
Finally, let's divide both sides by 10 to find x:
Answer: x = 3.5
