Answer:

40cm

Step-by-step explanation:

1. To find the missing leg, use the Pythagorean theorem a²+ b² = c² and substitute the numbers a² + 8² = 17².

2. So a = 15 since 17²-8² = 289 - 64 =225 and the square root of 225 is 15

3. Now that all the lengths have been found. So the perimeter of the right triangle is 40cm.

How do i find an equation for a line with an x-intercept of 4 and a y-intercept of -2
ivann1987 [24]

Answer:

The equation of a line is y = ax + b, where a is the slope and b is the y-intercept.  

Since we have the y-intercept, all we need to do is find the slope. To find the slope, you need 2 coordinates.

The y-intercept is where the line crosses the y axis, so it is where x is 0. Since the y intercept is -2, that means the first coordinate is (0, -2)

The x-intercept is where the line crosses the x axis, so it is where y is 0. Since the x intercept is 4, that means the second coordinate is (4, 0)

Since we already have the y-intercept, all we do is put the slope in the equation: y = 1/2x - 2.
