Select the lengths in centimeters that would form a right triangle
Ivenika [448]

Answer:

9, 40 and 41

Step-by-step explanation:

All right triangle have lengths that follow the Pythagorean Theorem (a²+b² = c²).  Right triangles have one angle equal to 90°.  The two shorter sides form the right angle and the side opposite the right angle is called the hypotenuse.  

Using the lengths given, we can use guess and check to see what sum of two sides squared would equal a third side, or just plug them into the equation: a²+b² = c² and see what lengths fit this equation.  

I recommend starting with squares you are familiar with:

9² + 40²= 81 + 1600 = 1681

Now, take the √1681 to find the length of 'c', or the hypotenuse:

√1681  = 41

Since these three lengths fit the Pythagorean Theoreom, the would form a right triangle.

What is the slope <br> y = (34/4)x + 3
statuscvo [17]

Answer:

The slope is 17 / 2.

Step-by-step explanation:

The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

y=mx+b

Find the values of m and b using the form y=mx+b.

m=17 / 2

b=3

The slope of the line is the value of m, and the y-intercept is the value of b.

Slope: 17 / 2

y-intercept: 3
