Answer:
28° (Answer A)
Step-by-step explanation:
Note that tan t = 8/15 = 0.533
Applying the inverse tangent function, we get
t = arctan 0.533 = 0.4900 radian
Mult. this by the radian-degree conversion factor results in: 28.072°
and when rounded off to the nearest degree, the measure of angle T is 28° (Answer A)
Answer:
r= -1,-2
t= -7,-4
s= -2,-8
Step-by-step explanation:
Answer: The .30 per mile is the independent, because it is manipulated, and changed throughout. DRY MIX : Dependent, Responding, Y axis. Manipulated, Independent, X axis.
Answer:
666 divided by 6 is 111. So, they would need 111 vans.

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°.
