-.5 + 2, you can think of this as 2 - .5 as well, it would equal out to be 1.5.
D/r , i think , i’m not sure if it is correct
The first term in the series is 336. The second term is obtained by subtracting 4 from the first term; subtract 4 from that to get the third term; and so on. Then the <em>n</em>-th term in the series is
336 - 4 (<em>n</em> - 1)
or
340 - 4<em>n</em>
The last term in this series is 4, so we solve for <em>n</em> :
340 - 4<em>n</em> = 4
336 = 4<em>n</em>
<em>n</em> = 336/4 = 84
The sum of the series is then
Recall that
Then the sum we want is
9514 1404 393
Answer:
b = 71 m
A = 83°
C = 29°
Step-by-step explanation:
Many calculators can solve triangles. Apps are available for phone and tablet, or on the internet, like the one used here. In general, it takes less time to use one of these than to type your question into Brainly.
Given two sides and the angle between them, the Law of Cosines is the appropriate relation to use for finding the third side.
b = √(a² +c² -2ac·cos(B))
b = √(76² +37² -2·76·37·cos(67.75°)) ≈ √5015.48
b ≈ 70.82005 ≈ 71 . . . meters
__
One a side and its opposite angle are known, the remaining angles are found using the Law of Sines.
sin(A)/a = sin(B)/b
A = arcsin(a·sin(B)/b) = arcsin(76·sin(67.75°)/70.82005) ≈ 83.33°
A ≈ 83°
C = arcsin(37·sin(67.75°)/70.82005) ≈ 28.92°
C ≈ 29°
Or, you can find the remaining angle from 180° -68° -83° = 29°.
