Answer:
Step-by-step explanation:
<u>We need to add up 4 angles to get 360.</u>
<u>Here is what you fill out for the missing boxes:</u>
- 70 + 70 = 130
- 70 goes into the smallest angle.
- 115 + 115 = 230.
- If we do 120 or 130, It would make 370 or 390.
- 130 + 230 = 360.
- 50 + 50 = 100.
- Missing 50 goes into smallest angle.
- 130 + 130 = 260.
- 260 + 100 = 360.
Answer: Let me tell you
Step-by-step explanation:
Instead of asking on Brainly go on Google and search up Symbolab just see the calculator website and see how it is it can solve an algebraic equation and it tells you how step by step and when I mean step by step I mean every STEP!
Answer:
Step-by-step explanation:
X^2 + 5x - 5 = 0
This is a quadratic equation that cannot be factored. It can be solved using the quadratic formula or by completing the square.
the quadratic formula is x = (-b +-sqrt(b^2 - 4ac))/2a
a is the coefficient of the x^2, b is the coefficient of the x, and c is the constant.
a = 1, b = 5, c = -5
x = (-5 +- sqrt(25+20))/2
x = (-5 +- sqrt(45))/2
x = (-5 + - 3 sqt 5))/2
x = (-5 + 3sqrt5)/2 and x = (-5 - 3sqrt5)/2
