The measures of the angles of a triangle are represented by 2x+15, x+20, and 3x+25. find the measures of the triangles

55°, 40° and 85°

Step-by-step explanation:

For a given triangle, the sum of its interior angles is equal to 180°.

Here, the interior angles are and .

∴

Now, plug in 20 for x and evaluate each angle.

So, °

°

°

Therefore, the measures of the angles of the triangles are 55°, 40° and 85°.

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
