What are the angle measurements of 6x + 1° = 3x + 11°
hodyreva [135]

Answer:

x=3\frac{1}{3}^\°

Step-by-step explanation:

Given equation:

6x+1\°=3x+11\°

To find the angle measure of x   

Solution:

In order to find the angle measure x , we will isolate x on left side by carrying out math operations on both sides.

We have:

6x+1\°=3x+11\°

Subtracting both sides by 3x  

6x-3x+1\°=3x-3x+11\°

 3x+1\°=11\°

Subtracting both sides by 1°.

3x+1\°-1\°=11\°-1\°

3x=10\°  

Dividing both sides by 3.

\frac{3x}{3}=\frac{10\°}{3}

x=\frac{10}3}^\°

Converting fraction to mixed number by dividing and writing the quotient as whole number and the remainder as numerator.

∴  x=3\frac{1}{3}^\°  (Answer)
