Step-by-step explanation:
By sum of angles on a straight line = 180°,
we have Angle A + Angle B = 180°,
Angle C + Angle D = 180°, and
Angle E + Angle F = 180°.
Hence Angles A + B + C + D + E + F = (180°) + (180°) + (180°) = 540°.
Answer:
the degree of x can be added to 120 to get 180. they form a straight line which is 180°. subtract 120 from 180 to get you answer.
180-120=60 so x=60
A) |–3| = 3 and –|–4| = –4
It’s the only one that makes sense.

Answer:
it is a convenience sample
Step-by-step explanation:
Answer:
- 20
Step-by-step explanation:
Step 1:
0.6r + 3 = 0.1r - 7 Equation
Step 2:
0.5r + 3 = - 7 Subtract 0.1r on both sides
Step 3:
0.5r = - 10 Subtract 3 on both sides
Step 4:
r = - 10 ÷ 0.5 Divide
Answer:
r = - 20
