Answer:
x = 2±3sqrt(3)
Step-by-step explanation:
(x-2)^2/3=9
Multiply each side by 3
(x-2)^2/3 *3=9*3
(x-2)^2=27
Take the square root of each side
sqrt( (x-2)^2)=±sqrt(27)
x-2 = ±3sqrt(3)
Add 2 to each side
x = 2±3sqrt(3)
The measurement of angle A = 52 ° .
In question we need to find angle A ,
To find angle A using Law of Sines :
Law of Sine : ( a / sin A ) = ( b / sin B ) = ( c / sin C ) where a , b and c are the sides opposite to angle A , B and C resp. of a triangle .
Applying Law of Sines ,
25 / sin A = 28 / sin 62
sin A = ( 25 * sin 62 ) / 28
sin A = 0.7883
Therefore , angle A = 52 ° .
Hence , the measurement of angle A = 52 ° .

The answer is exponential
Answer:
NO solution
Step-by-step explanation:
5(3x+9)−2x=15x−2(x−5)
Step 1: Simplify both sides of the equation.
5(3x+9)−2x=15x−2(x−5)
(5)(3x)+(5)(9)+−2x=15x+(−2)(x)+(−2)(−5)(Distribute)
15x+45+−2x=15x+−2x+10
(15x+−2x)+(45)=(15x+−2x)+(10)(Combine Like Terms)
13x+45=13x+10
13x+45=13x+10
Step 2: Subtract 13x from both sides.
13x+45−13x=13x+10−13x
45=10
Step 3: Subtract 45 from both sides.
45−45=10−45
0=−35
