Find the missing side length in the image below 12 18 and 10
1 answer:
The missing length of the right triangle is 13.41 inches.
<h3>How to find the side of a right triangle?</h3>A right angle triangle has one of its angles as 90 degrees.
The side length of a right triangle can be found using Pythagoras theorem.
Therefore,
c² = a² + b²
where
- c = hypotenuse
- a and b are the other legs.
Therefore,
x² = 18² - 12²
x² = 324 - 144
x² = 180
x = √180
x = 13.416407865
x = 13.41 inches

Answer:
The equation for the axis of symmetry is x=1.5.
Step-by-step explanation:
It is given that a quadratic function passes through the points ( − 5 , − 8 ) and ( 8 , − 8 ) .
In the given points y-coordinates are same, i.e., -8. It means both the points lie on the horizontal line y=-8.
If a quadratic function passes through two points (a,c) and (b,c), then the equation for the axis of symmetry is
According to the given points a=-5, b=8 and c=-8. Put these value in the above formula.
Therefore the equation for the axis of symmetry is x=1.5.
