Answer:
Here ANSWER
X+2x+5x = 56. Divide 56 by 8 to get 7 = x. First=7. Second=14, third=35
Step-by-step explanation:
Answer:
∠ DAB = 48°
Step-by-step explanation:
The sum of the 3 angles in Δ ACD = 180° , then
∠ CAD + 60° + 90° = 180° , that is
∠ CAD + 150° = 180° ( subtract 150° from both sides )
∠ CAD = 30°
Then
∠ DAB + ∠ CAD = ∠ CAB
∠ DAB + 30° = 78° ( subtract 30° from both sides )
∠ DAB = 48°
Answer:
Step-by-step explanation:
You will compose the functions (that is, plug x into one function, plug that function into the inverse function, and then simplify) and verify that you end up with just "x". Here's what it looks like: Determine algebraically whether f (x) = 3x – 2 and g(x) = (x + 2)/3 are inverses of each other.

Let us first find the angle adjacent to θ. To find this we can construct a right triangle by drawing a line segment from the point (-12,5) straight down to the x-axis. Using right triangle trig...
tan(adjacent angle)=5/12
adjacent angle=22.62 degrees
Since the two angles make a linear pair.
θ=180-22.62=157.38 degrees
cos(157.38 degrees) = -0.92
answer: -0.92
