What’s the value of x?

Because this triangle is an Isosceles triangle, two of the angles will be the same. You can tell this is an Isosceles triangle because two sides have the same length but the other does not. You can use this to make an equation. Because a triangle has 180 degrees all together, you can use the equation 2x+56=180. To solve for X you first do 180-56. You will get 124. Now you have 2x=124. You then divide 124 by 2. You will then get 62. This means X = 62 or 62 degrees. The final answer will be X = 62 Degrees.

Given the rectangular solid, RS = 6, ST = 3, and SL = 4. Solve for KT.
katrin [286]

First thing is that you need to find the diagonal of the rectangle

but remember is it a horizontal rectangle.

So let's start it :)

d= √6²+3²

d= √36+9

d= √54

d= 6.7082

But wait.. we are not done yet

We need to solve KT

we have 6.7082 which is the base and we have SL=4 which is the height

so with this 2 information we can find KT

KT is the hypotenuse because when you draw the line from K to T you'll see that it is the longest line.

Use the hypotenuse formula which is

C = √a²+b²

Now replace C by KT since we are solving for KT instead of C. Got it ?:)

KT= √6.7080²+4²

KT= 7.81


I do it with decimals so it might be little bit confusing to you but I think you can solve that different ways :)


Well I hope that's help and if not I am so sorry.

Z= -12i + 11 what are the real imaginary parts of z
Sergio039 [100]
Let's solve for i.

z=−12i+11

Step 1: Flip the equation.

−12i+11=z

Step 2: Add -11 to both sides.

−12i+11+−11=z+−11

−12i=z−11

Step 3: Divide both sides by -12.

−12i−12=z−11−12

i=−112z+1112

Answer:

i=−112z+1112
