Answer:
m∠a = 50°
Step-by-step explanation:
Since this is an isosceles triangle, we know that the other unknown angle is also 65°. Since all angles in a triangle add up to 180°,
180 - 65(2) = a
a = 180 - 130
a = 50°
Answer:
I am pretty sure it is when you have a sequence of numbers that you are subtracting or adding from by the same constant over and over
Step-by-step explanation:
an=a1+(n-1)d
d=common difference
an= the nth term in the sequence
a1 first term in the sequence. (Usually you can plug in 1, as the n, and work from there)
Answer:
95 m
Step-by-step explanation:
If the graph shows the height of the balloon after t minutes from beginning of descent, look to when t = 0. At t=0 it has not yet begun it's descent because no minutes have passed. At that point on the graph the height is 95 m (the point is (0,95))
701 = 21 + 68w
701-21= 680
680/68=10
w=10
