Answer:
<1=73
Step-by-step explanation:
All triangles add up to 180 degrees!
Add 20 and 87
20+87=107
Subtract 107 from 180
180-107=73
Hope this helps! :)
Answer:
180 - 55 = angle 1
80 - 55 = 25 so 180 - 55 = 125
angle 1 = 125 degrees
Answer:
a
Step-by-step explanation:
everything else there are gaps in between like b and in c they are overlapping
Answer:
C. f has a relative maximum at x = 1.
Step-by-step explanation:
A. False. f(x) is concave down when f"(x) is negative. f"(x) is the tangent slope of the graph, f'(x). So f(x) is concave down between x = -1.5 and x = 1.5.
B. False. f(x) is decreasing when f'(x) is negative. So f(x) is decreasing in the intervals x < -3 and 1 < x < 2.
C. True. f(x) has a relative maximum where f'(x) = 0 and changes from + to -.
