6(a+3)=18+6a    (distribute the 6)

6a+18=18+6a    (subtract 18 to both sides)

6a=6a    (divide 6 to both sides)

a=a    

When it's like this, you can see that whatever "a" value you plug in, it'll make the equation true. This means that a=infinitely many solutions

Hi,

Let's solve the equation step by step.

6(a+3)=18+6a

Step 1: Simplify both sides of the equation.

6(a+3)=18+6a

(6)(a)+(6)(3)=18+6a(Distribute)

6a+18=18+6a

6a+18=6a+18

Step 2: Subtract 6a from both sides.

6a+18−6a=6a+18−6a

18=18

Step 3: Subtract 18 from both sides.

18−18=18−18

0=0

Answer:

All real numbers are solutions.

Have a great day!

In an obtuse isosceles triangle the angle measurements are, x∘, x∘, and (10x−2)=128∘. Find the measurement of one of the acute a
klemol [59]

Answer:

26°

Step-by-step explanation:

An obtuse triangle is a triangle that has one obtuse angle. Obtuse angle is an angle that is greater than 90 degrees but less than 180 degrees.

An isosceles triangle is a triangle that has two equal sides and angles.  

Therefore, an obtuse isosceles triangle is a triangle with an obtuse angle and two equal sides that have two equal acute angles (angle less than 90° ).

Given:

The three angles of the triangle are given to be x°, x°  and (10x−2) = 128°. The obtuse angle is 128°, the two x° are acute angles. We are not using equation 10x − 2 since the value of the obtuse angle has been given as 128°

The sum of angles in a triangle is 180°

∴  x° + x° + 128° = 180°

2x° = 180° - 128°

2x° = 52°

x° = 52° / 2

x° = 26°

The measurement of one of the acute angles is 26°
