The answer is 1/2 (; do u need any more help?
Answer:
x°+2x°+(x-24)°=180°
Step-by-step explanation:
The sum of of the interior angles of all triangles add up to 180°
Adding x°, 2x°, and (x-24)° <em>will</em> equal 180
Therefore, an equation that can be used to solve for the missing angles is: x°+2x°+(x-24)°=180°
The solution as in where do they intersect? if so, it would be 0.0769 and -0.0769
The answer is 75! Explanation: Use the distance formula:)
Answer:
B
Step-by-step explanation:
Given a quadratic equation in standard form
ax² + bx + c = 0 ( a ≠ 0 )
Then the discriminant is
Δ = b² - 4ac
• If b² - 4ac > 0 then 2 real irrational roots
• If b² - 4ac > 0 and a perfect square then 2 real rational roots
• If b² - 4ac = 0 then 1 real double root
• If b² - 4ac < 0 then 2 complex roots
Given
x² + 3x - 7 = 0 ← in standard form
with a = 1, b = 3, c = - 7 , then
b² - 4ac
= 3² - (4 × 1 × - 7) = 9 + 28 = 37
Since b² - 4ac > 0 then 2 real irrational roots
