Solve the Equation.

<h2>1.</h2>

Firstly, combine like terms: 7r-8=10+r

Next, subtract r on both sides of the equation: 6r-8=10

Next, add 8 onto both sides of the equation: 6r=18

Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>

<h2>2.</h2>

Firstly, multiply both sides by e: TE=3u

Lastly, divide both sides by 3, and <em><u>your answer will be \frac{TE}{3}=u</u></em>

What is 3/2 x + 30 degrees
jekas [21]

Sum of internal angles of any triangle = 180∘

∴x + 2x + 3x = 180∘
∴6x = 180∘
∴ x = 30∘

So the angles are: 30∘, 60∘ and 90∘
