By angle, you're a scalene triangle, and by angle, youre an acute triangle
Answer: 5 seconds
<u>Step-by-step explanation:</u>
Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).
h(x) = -2x² + 20x + 48
a=-2 b=20 c=48
Axis of symmetry: x = 
= 
= 
= 5
Answer:
40 degrees
Step-by-step explanation:
If all triangles add up to 180°, the 180-104-36=40, so the answer is 40°
Plug in 3 for x. 5(3) (-2(3) x 2) = 15(-6 x 2) = 15(-12) = -180.
