Please please please answer this I have the answer I just need the work for it!!!!!
MrRa [10]

Answer:

x=80

Step-by-step explanation:

First of all, you must find the length of the side to add with 36 to equal 100. This would give you 64. So once you do that, you can do pythagorean theorem to find the length of x. This would give you 64^2 + 48^2 = x^2. Once you have this equation, you square your terms to get; 4,096 + 2,304 = x^2. After you add them you will now have 6,400 = x^2. Once you have this, you will need to do the square root of both sides of the equation; sqrt(6400) = x. This gives you x = 80.

Hope this helps!

Equations practice with angles Geometry. Can anyone help me please, im stuck....​
Bas_tet [7]

Same as the last one ! Review your parallel lines, and you'll see that angles A and B have to be equal. So you solve it EXACTLY the same way as the last one.

You say "A equals B", and that means that

8x - 10 = 3x + 90

Solve that to find x (it's 20),

and then use x to find angle B (it's 150; they both are).

(Don't just take my word for it. Please work it through.)
