Answer:
15.2
Step-by-step explanation:
Answer:
66
Step-by-step explanation:
Angle 2 and 4 are supplementary, so if angle 4 is 123, then 180-123=57.
So angle 2 is 57.
Then, if angle 2 and 3 are 57 and we know that all angles of a triangle have to add up to 180, then:
57+57+angle 1=180
114+ angle 1=180
angle 1= 66
Answer:
X<_200
Step-by-step explanation:
We know that if the number connot be more than 200 then the number is less than or equal to 200
This should be the correct solution
x + 4 = -8
x + 4 + (-4) = -8 + (-4)
x + 0 = -12
x = -12
