A shape with 4 equal sides.
Answer:
Step-by-step explanation:
Zeros α = -3 and β = -4
Quadratic equation: x² - (α + β)x + αβ = 0
x² - (-3-4)x + (-3)*(-4) = 0
x² - (-7)x + 12 =0
x² + 7x + 12 = 0
Answe
Step-by-step explanation:
The interior angles of a triangle add up to 180. We know from the photo that there is a 90° angle and an 18° angle, and 90-18 is 72, so the other interior angle is 72°. The question is asking you to find the value of side x, so you'll need to use sin.
sin (72°) = x/16
x ≈ 15.2
