Answer:
x =12
Step-by-step explanation:
The two angles are complementary, so the add to 90 degrees
5x+1/2x +24 = 90
Combine like terms
5 1/2 x +24 = 90
Subtract 24 from each side
5 1/2 x = 90-24
Change the mixed number to an improper fraction
11/2 x = 66
Multiply by the reciprocal 2/11 on each side
2/11 *11/2 x = 66*2/11
x = 6*2
x =12

Answer:
97°
Step-by-step explanation:
The sides that are equal are 4.6
One of the sides length is 4.6, and its opposite angle is 97. If there is another line that has a length of 4.6 in the same figure, it's angles should also be 97 degrees.
