I need help with angles
Answer:
1. ∠CFD = 28°
2. ∠RPQ = 53°
Step-by-step explanation:
For the first one:
∠CFD and ∠DFE are angles on a straight line
Angles on a straight line add up to equal 180
That being said we can find the missing angle (∠CFD) by subtracting the given angle measure (152°) from 180
so ∠CFD = 180 - 152
180 - 152 = 28
Hence, ∠CFD = 28°
For the second one:
Complementary angles have a sum of 90°
If ∠RPQ and ∠SPR are complementary angles we can find the missing angle ( ∠RPQ in this case ) by subtract the given angle measure ( 37° ) from 90
so ∠RPQ = 90 - 37
90 - 37 = 53
Hence , ∠RPQ = 53°
At the math store, one circle costs one amount, and each square costs another amount. 5 circles plus one square is 20 cents. How much would 12 circles plus 5 squares cost?
Answer: 61 cents
Step-by-step explanation:
Let’s assume a circle is X and a square is Y.
The problem states:
5x + 1y = 20
2x + 3y = 21
Taking the 1st equation we can see that
1y = 20-5x which is the same as
y = 20–5x
If we replace y in the 2nd equation with the above we get:
2x + 3(20–5x) = 21
which is the same as
2x + 60 - 15x = 21
we can rearrange to get
2x -15x = 21 -60
which is the same as:
-13x = -39
therefore x = -39/-13 or
x = 3
We can then calculate y
If y = 20–5x, then y = 20 -15
There y = 5
So to answer you question, 12 circles plus 5 squares =
12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents
hope this helps
If the point M(2,2) is reflected over the y axis, what will be the coordinates of the resulting point, M’?
Answer:

Answer:
10. y=102,
11. x=103
12. x=145
Step-by-step explanation:
10.) 120+85+53+y=360
y+258=360
y=102,
11.) 117+100+105+115+x=540
x+437=540
x=103,
12.) 129+116+120+125+135+130+x=900
755+x=900
x=145
Answer:
10.) 102 11.) 103 12.) 145
Step-by-step explanation:
I am assuming you need help on all three questions.
10.) This shape, a trapezoid, has 4 angles. Therefore these angles are going to all add up to 360 degrees.
To solve... 360 - 120 - 85 - 53 = 102
OR...
120 + 85 + 53 = 258 then... 360 - 258 = 102
11.)This shape, a pentagon, has 5 angles. Therefore these angles are going to all add up to 540 degrees.
To solve... 540 - 117 - 100 - 105 - 115 = 103
OR...
117 + 100 + 105 + 115 = 437 then 540 - 437 = 103
12.)This shape, a heptagon, has 7 angles. Therefore these angles are going to all add up to 900 degrees.
To solve... 900 - 116 - 120 - 129 - 130 - 135 - 125 = 145
OR...
116 + 120 + 129 + 130 + 135 + 125 = then... 900 - 755 = 145

Answer:
work shown is incorrect
Step-by-step explanation:
An equal sign is a sacred symbol. It needs to be treated with respect. The equal sign can only be used legitimately when the expression on one side is actually equal to the expression on the other side.
Here, you seem to have ...
16 -7 = 11 . . . . . FALSE
9 ≠ 11 . . . . . . . . why the equal sign should not be used
So, the inequality you're trying to solve depends on which of the "equal" values you intend.
7 + x < 16 - 7
Subtracting 7 from both sides gives ...
x < 2
This graphs as an open circle at x=2 and shading of the number line to the left from there. See the attachment for the graph.
__
7 + x < 11
Subtracting 7 from both sides gives ...
x < 4
This graphs as an open circle at x=4 and shading of the number line to the left from there. The graph is similar to the one attached, but has the point at x=4 instead of x=2.
__
Your solution
Somehow you have concluded that x < 11. If that is correct, and you want to graph that, you need to draw an open circle at x=11 (not x=12), and shade the number line to the left from that point. A solid dot at x=12 and a line left of that does not represent the inequality x < 11.
A solid dot is used only for the "or equal to" case. You have graphed x ≤ 12.
If ∠X and ∠Z are complementary, and the measure of ∠Z is 45°, what is the measure of ∠X?
Answer:
The measure of ∠X is 45°.
Step-by-step explanation:
Complementary angles are two angles that have a sum of 90°.
I subtracted 45 from 90 (90-45) and got 45°.

Step-by-step explanation:
The perimeter of a playing field for a certain sport is 174 ft. The field is a rectangle, and the length is 45 ft longer than the width Find the dimensions.
The width of the playing field is 20 ft.
(Type an integer or a decimal.)
Answer:
21 ft by 66 ft
Step-by-step explanation:
From the question,
P = 2(L+W)............... Equation 1
Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.
If the Length of the Field is 45 ft longer than the width,
L = 45+W............ Equation 2
Substitute Equation 2 into equation 1
P = 2(45+W+W)
P = 90+4W............. Equation 3
Given: P = 174 ft.
Substitute into equation 3
174 = 90+4W
4W = 174-90
4W = 84
W = 84/4
W = 21 ft.
Substituting the value of W into equation 2
L = 45+21
L = 66 ft.
Hence the dimensions of the playing field is 21 ft by 66 ft
