(a)
= 400
(b)
(c) Only the positive solution makes sense because you cannot have a negative side length.
(d) Since one side of the painting is 20 inches, all four sides together will be 20*4 = 80 inches
The answer is D.
If you multiply them all together the answer (without simplifying), it should equal 210/9, you then simplify the numerator and denominator by 3 and you get 70/3.
Andrew drove at 78 km/h
Brian drove at 83 km/h
234/83 = 2.819 hours, or 169 minutes.
180-169=11
Answer:
9°
Step-by-step explanation:
You can make use of any of the trigonometric ratios to determine N, or you can let your calculator tell you what it is by solving the triangle.
SOH CAH TOA reminds you that
... sin(N) = 13/85 . . . . N = arcsin(13/85)
... cos(N) = 84/85 . . . N = arccos(84/85)
... tan(N) = 13/84 . . . . N = arctan(13/84)
all will tell you N ≈ 8.79741° ≈ 9°
