Answer:
The angles are 79.45, 59.02 and 41.53 degrees to the nearest hundredth.
Step-by-step explanation:
We have a triangle with sides of length 8.6, 5.8 and 7.5 feet.
Using the Cosine Rule to find the measure of the angle opposite the side of length 8.6 feet:
cos X = (8.6^2 - 5.8^2 - 7.5^2) / ( -2*5.8*7.5)
= 0.18310
X = 79.45 degrees.
We can now find another angle using the sine rule:
8.6 / sin 79.45 = 7.5/ sin Y
sin Y = (7.5 * sin 79.45) / 8.6
Y = 59.02 degrees
So the third angle = 180 - 79.45 - 59.02
= 41.53 degrees.
The answer should be A. 4.5
Because line x is just over half of the length of the line that is 8ft
Answer:
the answer is A because it's pace at the y axis
PT=ST and QT=TR, when angles are verticals their opposite arcs are equivalent. i think. someone feel free to correct me if this is wrong
You traveled 315 miles because 70 miles times 4.5 hours would be 315
