Somebody please help i literally can’t solve this and it’s been an hour:( giving big brainlest!

To solve for this problem we must know the unique property of triangle which is their sum of angles tends to 180°.

We've been given three angles in figure which are 2x, x + 84 and 3x. Now let's tend their sum to 180°.

x = 25/2304

step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
