68 degrees because 56×2=112 then 180-112=68

The sum of all angles of a triangle is equal to 180°

On a isosceles triangle, the base angles are the same.

We add them together 56° + 56° = 112°

To know X, we subtract 112° from the total

180° - 112° = 68°

X = 68°

OR as an equation

56 + 56 + x = 180
112 + x = 180
x = 180 - 112
x = 68

A fisherman can row upstream at 5mph and downstream at 10mph he started rowing upstream until he got tired and then rowed downst

AlekseyPX

We have been given that the upstream speed is $5 mph$ and the down stream speed is $10mph$ .

Let the fisherman traveled a distance of x miles.

The total time of the trip is 6 hours.

Relations between speed (s), time (t) and distance (d) is $s = \frac{d}{t}$

Hence, $t= \frac{d}{s}$

Time upstream + time downstream = 6

$\frac{x}{5} +\frac{x}{10} =6$

lcm = 10

$\frac{2x+x}{10} =6$

=> $\frac{3x}{10} =6$

Cross multiplying, $3x= 60$

x = 20 miles .. Answer.
