Answer:
obtuse
Step-by-step explanation:
if one angle is 25 and the other 50, then the third angle is 105, because all three angles have to add up to 180. So it is a obtuse triangle.
Answer:
P= A + B + C
Step-by-step explanation:
P= Side + base + Side
P= 10 + 6 + 8
P = 24
Answer:
t = -1, 2
Step-by-step explanation:
Step 1: Define
h(t) = -5t² + 5t + 10
Step 2: Factor
h(t) = -5(t² - t - 2)
h(t) = -5(t - 2)(t + 1)
Step 3: Find roots
0 = -5(t - 2)(t + 1)
0 = (t - 2)(t + 1)
t - 2 = 0
t = 2
t + 1 = 0
t = -1
