Two supplementary angles are in the ratio 3:7. Find the angles ?
Let the two angles be 3x and 7x.
Supplementary angles add up to 180 degrees.
Therefore:
3x + 7x = 180
10x = 180
x = 18
3x = 3 * 18 = 54
7x = 7 * 18 = 126

Answer:
-10
Step-by-step explanation:
(-4) + 4 + (-20) - (-10) = (-4) + 4 + (-20) + 10
= 0 + (-10)
= (-10)
(-4) + 4 = 0
-20 + 10 = -10. When two numbers have different sign, subtract and the result will have the sign of the bigger number. Here bigger number is 20 and So the result has a negative sign
