A right triangle whose acute angles have measures 5x and 4x.
rewona [7]

Answer:

x=10

50 and 40

Step-by-step explanation:

The sum of the angles of triangle is 180

90 +5x+4x = 180

Combine like terms

90 +9x =180

Subtract 90 from each side

9x = 180-90

9x = 90

x = 90/9

x = 10

The angles are 5x = 5*10 =50  and 4x = 4(10)= 40

melisa1 [442]

Answer: Never true. 24 times 12 is 288, however the LCM for them is 3. 8 times 20 is 160, however the LCM for them is 2.

Step-by-step explanation:

If you look at it by the fact that every number has a LCM of 1, and every even number has an LCM of 2, it is easy to take that and apply it to this question. Just factor in the numbers.
