Answer:
<h2>b = 60</h2>
Step-by-step explanation:
We know: The sum of measures of angles in a triangle is equal to 180°.
Therefore we have the equation:
b° + 80° + 40° = 180° <em>combine like terms</em>
b° + 120° = 180° <em>subtract 120° from both sides</em>
b° + 120° - 120° = 180° - 120°
b° = 60°
Answer:
So dogs have 4 legs, ducks have 2
If three dogs have 12 legs, then one duck has 2, so total 14 legs, and 4 animals
4+4+4= 12+2=14
So 3 dogs and 1 duck :)

Answer:
2.75 seconds and 133 feet
Step-by-step explanation:
We require to find the coordinates of the vertex of the parabola
the t coordinate ( time ) for a quadratic in standard form is
= - 
with a = - 16 and b = 88
t = - 
= 2.75 seconds ← time taken to reach max
to find the max height evaluate f(2.75 )
f(2.75 ) = - 16( 2.75)² + 88(2.75) + 12 = - 121 + 242 + 12 = 133 feet
