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.
Answer:
-1 is the answer , your welcome haha
Not A C or E So maybe B or D hope this helped a little
Your answer will be 2 2/4. If you want it simplified it will be 2 1/2
Answer:
13w/3
Step-by-step explanation:
1/3 w+ 4w =( 1/3 + 4) w = (1+12)/3 w = 13/3w
