Step-by-step explanation:
-3x + 27= -3
-3x = -3-27
-3x = -30
x= 10
So, Cot is negative in second and fourth quadrant.
So, tan(x+
)=-cot(x)
Option B
Answer:
x = 27
Step-by-step explanation:
∠ CAD and ∠ EDF are corresponding angles and are congruent, so
∠ CAD = 2x
The sum of the 3 angles in Δ ABD = 180°
sum the angles and equate to 180
72 + 2x + 2x = 180
72 + 4x = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
1:4 and 6:24 because 3/3=1 and 12/3=4 and 6/2=3 and 24/2=12
You need to have the common denominator and once you do see how many times the 1/6cup will go into the 7/8cup which is 5
