Step-by-step explanation:
DB length = 5 1/4 + 2/3
=21/4 + 2/3
= 63/12 + 8/12 = 71/12
CD length = 5 1/4 -2 = 3 1/4

Answer:
Right angle triangle
Step-by-step explanation:
- Given triangle is right angle triangle
- It is a type of triangle that has one of it's angles equal to 90 degrees.
- The other two angle sum up to 90 degrees.
- Here AC side is perpendicular and the AB side is base of the triangle.
- And the third side that is called CB which longest side of all three sides that is called hypotenuse.
Answer:
(-7,-4)
Step-by-step explanation:
There are 2 different ways to solve a system of equations and the one I'm going to show you will work for all systems. To start we will solve one of the equations for either X or Y it doesn't matter which one so I will choose the second one. Divide both sides by negative 4 and you will have the solved equation. x=1+2y Now we know what x equals so we can plug "1+2y" into the other equation where we see an X and we will get -8(1+2y)=24-8y and since we only have one variable now we can solve to get what Y is. The first step is distributing -8-16y=24-8y now lets put the Y's together on one side and the numbers together on the other -32=8y and just divide both sides by 8 to get the value of Y -4=y Now that we have Y we can plug -4 into either equation as Y to get the value of X I will use the second equation. -4x=-4-8(-4) and solve for X -4x=-4+32 -4x=28 x=-7 So now we have x and y and we can write it as out solution (-7, -4)
