Triangle j k l is shown. angle k j l is a right angle. angle j k l is 52 degrees and angle k l j is 38 degrees. given △jkl, sin(38°) equals cos(38°). cos(52°). tan(38°). tan(52°).

In what form is the following linear equation written y=9x+2

Each person in an it department of 25 people works on at least one of 3 major projects: system security, program implementation, platform development. 10 people work on system security, 13 work on program implementation, and 12 work on platform development. 4 people work on system security and platform development, 5 people work on program implementation and platform development, and 2 people work on all three projects. how many people work on system security and program implementation?

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.
