A triangle with two congruent sides is always a 45-45-90 triangle. A. True B. False
2 answers:
Answer:
False
Step-by-step explanation:
1) If a triangle has two congruent sides, then we are dealing with an isosceles triangle. If a triangle has two congruent sides and it is a 45º,45º,90º it's a special case of an isosceles triangle called Right Isosceles Triangle.
The Sum of its interior angles must be equal to 180º always!
2) Check it out below an example of an Isosceles Triangle. ∠E≅∠G

Answer:
The squirrel maximum height (h) = 21.125 ft
Step-by-step explanation:
The objective of this question is to determine the squirrel's maximum height.
Given that:
h = -2t² + 9t + 11
Differentiating h with respect to t, we get;
At the time dh/dt = 0, the velocity is maximum
Thus;
-4t = -9
4t = 9
t = 9/4
t = 2.25 seconds
From;
h = -2t² + 9t + 11
h = - 2(2.25)² + 9(2.25) + 11
h = - 10.125 + 20.25 + 11
h = 21.125 ft
