Complete question is;
The lengths of two sides of a right triangle ABC are given.
Find the length of the missing side.
b = 16 ft and c = 30 ft
Answer:
25.377 ft
Step-by-step explanation:
From online sources, c is the hypotenuse of the triangle.
Thus, we can use pythagoras theorem to solve for the other side of the right angle triangle.
c² = a² + b²
Where a is the length of the missing side.
Thus;
30² = a² + 16²
a² + 256 = 900
a² = 900 - 256
a² = 644
a = √644
a = 25.377 ft
12^2 +b^2 = 20^2 because of the Pythagorean theorem
144 + b^2 =400
B^2 =256
B=16
Pythagorean theorem
a^2 + b^2 = c^2
Squared of the smaller two sides is equal to the squared largest side
a = 6, c = 14
6^2 + b^2 = 14^2
36 + b^2 = 196
b^2 = 160
b = squareroot of 160
Solution: 12.6
Answer:
The width of the picture is 6 cm
Step-by-step explanation:
The length of the picture cm
The width of the picture cm
The length of a picture is 8 times the difference of the width and 4, so
- the difference of the width and 4 cm
- 8 times the difference of the width and 4 cm
- the length of the picture is 8 times the difference of the width and 4, so
Divide the equation by 8:
Rewrite it:
Add 4:
I believe the answer is their initial time was 8.46
