You can take the mean of each category (assuming it is evenly distributed) and calculate the mean as (10x4 + 30x3 + 50x2 + 70x1) / (4+3+2+1) = 300/10 = 30

Help please! ill mark brainliest
lesya [120]

Answer:

90deg

Step-by-step explanation:

If the angles are supplementary, that means mA + mB = 180*

we know that

mA = (2x + 8)deg

mB = (2x + 8)deg = mA

mA + mB = 180deg

mB + mB = 2mB = 180deg

mB = 90deg

Note, that we did not need to compute x even, because the angles were the same.
