Answer:

20 degrees

Step-by-step explanation:

Because lines CB and DA cross in the center of the circle, they are vertical angles and they are equidistant from arcs AB and CD. This means that CD and AB are congruent, and that therefore CD=AB=20 degrees. Hope this helps!

Use the substation to solve the system of equations. Y=x+1.75 4x-2y=4
beks73 [17]
So we need to plug in y into our equation so our new equation is:

4x - 2(x+1.75) = 4

first lets distribute the 2 by multiplying the values inside the parentheses by 2

4x - 2x + 3.5 = 4

4x - 2x = 2x

so now our equation is 2x + 3.5 = 4

we need to get x by itself on one side of the parentheses so lets move the 3.5 by subtracting by 3.5 on both sides

2x + 3.5 = 2x
4 - 3.5 = .5

new equation: 2x = .5

now to get rid of this 2 (being multiplied by x) we simply have to do the opposite - divide by 2 on each side

2x/2 = x
.5/2 = .25

so our x value is equal to .25!

The area of each triangular face of this right triangular prism is 8cm^2(squared).
otez555 [7]
Nothing is shown.
The triangle is a right triangle, 9, 12 & 15.
The triangle's area = b*h/2 = 9*12/2 = 54 sq meters each end.

------------
The 3 rectangles are 10 by 9, 12 & 15
Area of the 3 = 10*(9 + 12 + 15) = 360 sq meters
-----
Total area = 360 + 2*54
= 468 sq meters
