How many triangles can be constructed with angles measuring 80 degrees, 80 degrees and 40 degrees
bagirrra123 [75]

Answer:

Infinite triangles

Step-by-step explanation:

A triangle can have angles which total to 180 degrees

When one triangle ABC is constructed with degrees 80, 80 and 40 respectively, then similar triangles can be formed by transforming ABC with a real scale factor say k

k can take any real values positive, negative, rational, irrational etc.

Hence we can say given a triangle ABC with given angles there can be an infinite number of triangles with the same angles which will be similarl to ABC and carry an equal proportion with corrresponding sides.

$258.75

Step-by-step explanation:

Willie was being paid $24,895 per year, and he will get $28,000, let's find the difference.

$28,000 - $24,895 = $3,105       So he will be making $3,105 mor per year. THere are 12 months in a year so we need to divid our answer by 12.

$3,105/12 = $258.75

He will make $258.75 more per month if he takes the new job.
