Answer:
All of them are irrational except √9 which is rational.
Step-by-step explanation:
√5= 2.2606797749(irrational)
√9=3(rational) this one is rational
√7=2.64575131106(irrational)
√3.31662479035(irrational)

The point-slope form:
We have the points (3, -4) and (5, 1). Substitute:
The standard form: 
<em>multiply both sides by 2</em>
<em>use distributive property</em>
<em>subtract 2y from both sides</em>
<em>subtract 15 from both sides</em>
<h3>Answer: 5x - 2y = -7</h3>
To solve this, notice that you have the angle component (I will call this a) and the x-component (the distance of you from the building) of a trig formula, and you are looking for the y-component. We will use the tangent formula, since this incorporates the angle, x, and y components.
1. Write the formula
tan(a) = y ÷ x
2. Rewrite to include the known values.
tan(79.9) = y ÷ 100
3. Solve for the unknown variable, y.
tan(79.9) × 100 = y ÷ 100 × 100
tan(79.9) × 100 = y
4. A fancy step that I call the "flip flop."
y = tan(79.9) × 100
5. Use a calculator to find the value (make sure the calculator is in "degree" and not "radians" mode).
y = 561.3968
6. Round the number as is appropriate for this problem.
Have a great day!
Answer:
The answer to your question is: 40°
Step-by-step explanation:
Due to the directions, we can know that KL is parallel to GH, then the
∠ FKL ≡ ∠ FGH = 40
