Answer:
x = 14.02 units
Step-by-step explanation:
Finding unknown value using Pythagorean theorem:
This is an isosceles trapezium. The two perpendiculars divide the trapezium into two congruent triangles and a rectangle. Let the base of the triangle by 'y'. We can find the value of 'y' using Pythagorean theorem.
In ΔABC,
AC² = AB² + BC²
19² = 17 ² + y ²
361 = 289 + y ²
361 - 289 = y ²
y ² = 72
y =√72
y = 8.49
x = 31 - 8.49 - 8.49
x = 14.02
Answer:
ft
Step-by-step explanation:
A Cheetah can run at 103 ft/s.
A Zebra can run at x ft/s.
We have to use distributive property, in the distributive property we multiply a sum by multiplying each addend separately and then add the products.
In ten seconds, Cheetah will cover,
In ten seconds, Zebra will cover,
So the distance by which Cheetah is farther than Zebra is,
= (Use of distributive property)
