Step-by-step explanation:
To find your answer you first have to multiply the numbers that aren’t in parentheses and you multiply 2 and 7 and you get 14 then you don’t have to worry about the x because it is a variable so now add -4 +2. but first we have to turn negative into positive so you add -4 + 8
Answer:
130
Step-by-step explanation:
The two angles add up to 180 since they form a straight line
4y-50 + 3y+55 = 180
Combine like terms
7y +5 = 180
Subtract 5 from each side
7y-5+5 = 180-5
7y = 175
Divide each side by 7
7y/7 =175/7
y =25
The obtuse angle is greater than 90 degrees
3y+55
3(25) +55
75+ 55
130
