Monica [59]4 years ago
6 0

Answer: Answer is in the steps

Step-by-step explanation:

The interior angles of a triangle add up to one 180 degrees so they all have to add up to 180 degrees.

A)  (x+10)° + 50° + (x+20)° = 180°

B) Now solve for x  using the equation

   x+10 + 50 +x+20= 180  

    2x + 80 = 180

            -80   -80

2x = 100  

x = 50

umka21 [38]
Decimal places mean we just start counting immediately after the decimal point, so:
2dp: 0.00
1dp: 0.0

Significant figures, we start counting starting at the first non zero number
So we start counting at the 9, therefore:
2sf: 0.00097
3sf: 0.000965
