Problem 1
Answer: Choice B) angle1 = 26, angle2 = 64----------
Explanation:
Complementary angles add to 90
(angle1)+(angle2) = 90
(5x+6)+(68-x) = 90
4x+74 = 90
4x = 90-74
4x = 16
x = 16/4
x = 4
So,
angle1 = 5x+6 = 5(4)+6 = 26
angle2 = 68-x = 68-4 = 64
Note how
angle1+angle2 = 26+64 = 90

==========================================
Problem 2
Answer: Choice D) BC, AC, AB----------
Explanation:
The shortest side of a triangle is always opposite the smallest angle.
The longest side of a triangle is always opposite the largest angle.
Based on those two facts, we can say the shortest side is BC (since angle A = 53 is the smallest angle) and the longest side is AB (since angle C = 70 is the largest)
The order from smallest to largest is
BC, AC, AB
==========================================
Problem 3
Answer: Choice D) B < C < A----------
Explanation:
Use the reverse of the idea from problem 2. We know that AC is the smallest side which must mean that angle B is the smallest angle. Since BC is the largest side, angle A must be the largest angle.
The order of the angles is B < C < A
==========================================
Problem 4
Answer: Choice A) angle 5 = 50, angle 8 = 130----------
Explanation:
The same side exterior angles must be supplementary to have parallel lines.
==========================================
Problem 5
Answer: Choice A) angle G is the smallest----------
Explanation:
Use the same idea as problem 2. The smallest angle is opposite the smallest side. The smallest side is 48, so angle G being opposite of that side, is the smallest angle.
Angle O would be the largest as it is opposite the largest side DG = 70

On Monday, Sarah has to meet her friend at the park after school The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
house?
Answers
Answer:
8x + 4 - z
Step-by-step explanation:
Given the following :
The distance from her house to school is 2x+5 The distance from the school to the park is z If the total distance she was that day is 10x +9 how far is it from the park back to her
Distance from house to school = 2x + 5
Distance from school to park = z
Total distance covered = 10x + 9
Distance from park to house =?
Total distance = (distance from house to school + distance from school to park + distance from park to house)
Let p = distance from park to house
10x + 9 = (2x + 5 + z + p)
10x + 9 - 2x - 5 - z = p
8x + 4 - z

A and B are vertical angles. If mA=(7x-20° and mB =(6x-1)º, find the
measure of A.
Answers
Answer:
[tex]\angle A=113\textdegree[/tex]
Step-by-step explanation:
We know that ∠A and ∠B are vertical angles.
Remember that vertical angles have the same measure. So:
[tex]\angle A=\angle B[/tex]
Substitute them for their equations:
[tex]7x-20=6x-1[/tex]
Solve for x. Add 20 to both sides:
[tex]7x=6x+19[/tex]
Subtract 6x from both sides. So, the value of x is:
[tex]x=19[/tex]
To find ∠A, we can use its equation again:
[tex]\angle A=7x-20[/tex]
Substitute 19 for 7:
[tex]\angle A=7(19)-20[/tex]
Multiply and subtract:
[tex]\angle A=133-20=113\textdegree[/tex]
So, the value of ∠A is 113°.

A student did an experiment to determine the number of letters recognized on an eye chart to see if it was affected by distance. What is the independent and dependent variable in this experiment?
Answers
Answer:
Independent variable: distance
Dependent variable: number of letters recognized on an eye chart
Step-by-step explanation:
Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.
Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.
Since the hypothesis is that the distance affects the number of letters recognized,
the distance causes a change in the number of letters recognized not the other way around.
Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

What is the vertex of this parabola?
y-5 = x^2?
Answers
====================================================
Work Shown:
y-5 = x^2
y = x^2 + 5 ... add 5 to both sides
y = 1x^2 + 5
y = 1(x-0)^2 + 5 ... x replaced with (x-0)
The equation is now in the form y = a(x-h)^2 + k
We have a = 1, h = 0, k = 5.
The vertex is (h,k) = (0,5)
The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.
