Answer:
h = 16 feet
Step-by-step explanation:
Pythagoras´ theorem establishes, that in a right triangle square of the hypothenuse (c²) is the sum of leg ( b²) plus leg (a²)
Then
c² = a² + b²
where according to the problem statement
(20)² = h² + (12)² ( h is the height of the flagpole )
h² = 400 - 144
h² = 256
h = √ 256
h = 16 feet

Step-by-step explanation:
Answer: x-intercept is (4,0) and the y-intercept is (0,10)
Step-by-step explanation:
120/2=60 (sum of both lengths)
4x+4=60
