Answer:
Step-by-step explanation:
Sum of all angles of triangle = 180
39 + 102 + x = 180
141 + x = 180
Subtract 141 from both sides
x = 180 - 141
x = 39
Hi!
3x - 30 = x + 10
<h3>Solve by isolating x on one side. </h3><h3>Add 30 to both sides. </h3>
3x - 30 + 30 = x + 10 + 30
3x = x + 40
<h3>Subtract x from both sides. </h3>
3x - x = x - x + 40
2x = 40
<h3>Divide by 2 on both sides</h3>
2x/2 = 40/2
<u>x = 20</u>
<h2>The answer is x = 20</h2>
Hope this helps! :)
