Answer:
a. 6 feet
b. The length of the angle bisector of angle A is approximately 7.81 feet
Step-by-step explanation:
a. The given parameters of the right triangle ABC are;
The length of the leg AC = 5 ft.
The length of the hypotenuse AB = 13 ft.
Therefore, the length of the side BC = √((AB)² - (AC)²) = √((13 ft.²) - (5 ft.²)) = 12 ft.
The length to the middle of the side BC = BC/2 = (12 ft.)/2 = 6 ft.
b. The length of the angle bisector of angle A = The the length of the median from A to the side BC = √((BC)/2)² + (AC)²)
BC = √(((12 ft.)/2)² + (5 ft.)²) = √61 ft. ≈ 7.81 ft.
Answer:
3( r - 7s)
= 3r - 21s
Step-by-step explanation:
To find the answer we have to find the difference between the two numbers, divide it by 2 then add it back into the original number ... Let me show you.
1500 - 1250 = 250
250 ÷ 2 = 125
1250 + 125 = 1375
1375 is half way between 1250 and 1500
