Answer:

? = 70°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

120° is an exterior angle of the triangle, then

? + 50° = 120° ( subtract 50° from both sides )

? = 70°

missing angle = 70 degrees

Step-by-step explanation:

180 -120 =60, because supplemenatery angles add up to 180 degrees.

sum of all angles of a triangle = 180. so 180-60-50=70 degrees

40\times 1.25x\times 2.20x\times 3.2040×1.25x×2.20x×3.20

(40)1.25x2.20x3.20

+ − .   ln > <

× ÷ /   log ≥ ≤

( )    logx = %

1 Take out the constants.

(40\times 1.25\times 2.20\times 3.20)xx(40×1.25×2.20×3.20)xx

2 Simplify  40\times 1.2540×1.25  to  5050.
