Answer:
Step-by-step explanation:
Triangle CDE is a right angle triangle.
From the given right angle triangle
CE represents the hypotenuse of the right angle triangle.
With ∠C as the reference angle,
CD represents the adjacent side of the right angle triangle.
DE represents the opposite side of the right angle triangle.
To determineTan C, we would apply trigonometric ratio
Tan θ = opposite side/adjacent side. Therefore,
Tan C = 80/39
Tan C = 2.0513
Rounding up to the nearest hundredth, it becomes
2.05
Answer:
The answer is 3! I believe.
Step-by-step explanation:
-69>22 or 224 is what I think the answer is not too sure
Hello!
Angles 3 and 1 are vertical angles, and angles 2 and 4 are vertical angles. Vertical angles are congruent by definition, so angle 3 is congruent to angle 1, and angle 2 is congruent to angle 4.
The adjacent angles are supplementary (they add to equal 180 degrees) so you can set up an equation to solve for x.
180 = 2x + x
180 = 3x
60 = x
x = 60
To find the measure if each angle, plug in x as needed.
Angle 4 = x
Angle 4 = 60 degrees
Angle 2 = angle 4
Angle 2 = 60 degrees
Angle 3 = 2x
Angle 3 = 2(60)
Angle 3 = 120
Angle 1 = angle 3
Angle 1 = 120
I hope this helps you.
To multiply rational expressions you just multiply tops and multiply the bottoms so
5/2x+1 * 6/x = 30/2x^2+x
