ABCDE is a Pentagon with BE parallel to CD and BC parallel to DE. BC is perpendicular to CD. if the perimeter of ABCDE is 21cm. Find the value of x and y.

The sides and classifications of a triangle are given below. The length of the longest side is the integer given. What value(s) of x make the triangle? x,x, 8; right Please provide an explanation as well. Thank you.

The endpoints of the diameter of a circle are (-6,2) and (10,-2). What are the coordinate of the center of the circle?

**geometry**

in each circld, find the value of x. then find the given measure m<M.

what are the equation of a line through (8,-3) and passing distance square root of 10 from (3,2)

suppose the bases of the rectangle and triangle in the building above are doubled to 40ft,but the height of each figure remains the same.How is the force of the wind against the side of the building affected?

How do we know that C and B are complementary I'm trying to prove that for triangles (in this case a right triangle) that the sum of all of the their angles add up to 180 also what about the physics tiranlge

Thanks =] what about the physics triangle

**Geometry**

In my book there's a picture of an equalderal triangle. This is given information. Inside the triangle all three altitudes have been drawn to find the center point of gravity. The incircle is drawn. The circumcircle is drawn. Given that the radius of the incricle is 1, wha...

There is a right triangle. the legs are x and y and the hypotenuse is 120. the angle opposite x is 58. please check my answer. x= 120 y=64 because: SIN58= x/120 COS58=y/120

**Chem**

hah funny thing. i put geometry instead of my name cus geometry was my question but my names anna. =P but no problem

**Chem**

don't you have to balance out both sides of the equation? i could be wrong but wouldn't it be 2Fe(OH)^2 + H^2O^2 => 2Fe(OH)^3
