Could you find a way to share the illustration of this triangle?

Three angles are given:  8x, 2x+3 and 30 degrees. 

Use this rule:  the sum of the three angles of a triangle is 180 degrees.

Can you use this fact to solve for x?     By the way, I'm not convinced that there are 2 answers.  What makes you think there are 2?

Alex
Hello!

1 minute 3 seconds = 63 seconds

We must found out 63 is 90% of what number, using the percentage formula:

90 * 100 / 63 = 70

70 seconds = 1 minute 10 seconds

So, Niki's time for one lap is 1 minute 10 seconds (70 seconds).
