∠C and ​ ∠D are equal.

so  −x+26 =2x-10

-3x=-36

x=36/3

x=12°

∠D= 2x-10

put value of x here

∠D=24-10

∠D=14°

Vertical angles are made by two intersecting lines .and they are always equal
<span>∠C and ​ ∠D are equal.
so  </span><span>−x+26 =2x-10
-3x=-36
x=36/3
x=12</span>°

∠D= 2x-10
put value of x here

How do you measure the diameter of four steel rods and than compare the measurement? Thank you!
enyata [817]
The answer is B. 0.25 inch. Lets multiply all of them by the same factor. Since A. and B. have 3 decimals, lets divide all numbers by 1000: A. 0.026 * 1000 = 26, B. 0.25 * 1000 = 250, C. 0.24 * 1000 = 240, D. 0.025 * 1000 = 25. So, by comparing the whole numbers, it can be concluded that the biggest steel rod is B. 0.25 inch.
