Find the value of x.
azamat

Answer:

98 °

Step-by-step explanation:

We know that the sum of the angles in a triangle is 180. We also know that angle DAB is 122°, meaning that angle CAB is 180-122, which is 58°. We also know that angle CBA is 24 degrees. Therefore, angle x is just 180-(58+24), which is 98

Two marathon runners run the full distance of the marathon, approximately 26 miles, in 4 hours.
xxTIMURxx [149]

Answer:

6.5 miles in 1 hour and they will run 75% of the full distance in 1 hour.

Step-by-step explanation:

The distance covered by two marathon runners = 26 miles

They takes 4 hours

We need to find how many miles did they run in 1 hour

In 4 hour, the distance covered is 26 miles

To find distance covered in 1 hour, divide 26 by 4 such that.

d=\dfrac{26}{4}\\\\d=6.5\ \text{miles/hour}

So, they will cover 6.5 miles in 1 hour.

For percentage,

\%=\dfrac{26-6.5}{26}\times 100\\\\=75\%

So, they will run 75% of the full distance in 1 hour.
