Answer:
(5). [tex]\theta=36.86^{\circ}[/tex] (6) H = 25 units
Step-by-step explanation:
Given that,
Height of triangle, H = 15
Base, B = 20
(5)
We need to find the value of tanA.
[tex]\tan A=\dfrac{P}{B}\\\\\tan A=\dfrac{15}{20}\\\\A=\tan^{-1}(\dfrac{15}{20})\\\\A=36.86^{\circ}[/tex]
(6)
For a right angled triangle, Pythagoras theorem will be applicable as follows :
[tex]H^2=B^2+h^2\\\\H^2=20^2+15^2\\\\H=\sqrt{20^{2}+15^{2}}\\\\H=25\ \text{units}[/tex]
Hence, this is the required solution.

(a) Choose a length between 5 cm and 15 cm for the walking trail on the second map: ________cm.
(b) Determine the scale factor from the first map to the second map.
(c) A landmark on the first map is a triangle with side lengths of 3 cm, 4 cm, and 5 cm. What are the side lengths of the triangle landmark on the second map?
(d) Draw one of the triangles from part C. Label the side lengths and vertices accordingly. You may use this drawing tool or draw your triangle on paper:
Answer:
(a) Length = 4cm
(b) Scale factor = 0.5
(c) 3cm, 4cm and 5cm are represented by 1.5cm, 2cm and 2.5cm respectively, on the second scale
(d) See attachment for triangle
Step-by-step explanation:
(a) Choose a length between 5 cm and 15 cm
[tex]Length =4cm[/tex] --- This is solely up to you (you can make use of any length between 5 cm and 15 cm)
(b) The scale factor
The scale factor (k) is calculated as:
[tex]k = \frac{New\ Length}{Old\ Length}[/tex]
[tex]k = \frac{4cm}{8cm}\\[/tex]
[tex]k = 0.5[/tex]
(c) What are side lengths of 3 cm, 4 cm, and 5 cm on the second landmark
Using:
[tex]k = \frac{New\ Length}{Old\ Length}[/tex]
The old lengths, in this case are: 3cm, 4cm and 5cm
Make New length the subject
[tex]New\ Length = k * Old\ Length[/tex]
When [tex]Length = 3cm[/tex]
[tex]New\ Length = 0.5 * 3cm = 1.5cm[/tex]
When [tex]Length = 4cm[/tex]
[tex]New\ Length = 0.5 * 4cm = 2cm[/tex]
When [tex]Length = 5cm[/tex]
[tex]New\ Length = 0.5 * 5cm = 2.5cm[/tex]
So: 3cm, 4cm and 5cm are represented by 1.5cm, 2cm and 2.5cm respectively, on the second scale

Rosario is working on an 8-foot-by- 8-foot floor covered with 64 white tiles. She replaces x white tiles with blue tiles. After she's finished, there are 40 white tiles left. Write and solve an equation to find the number of blue floor tiles Rosario used.
Answers
Answer: 24 blue tiles.
Step-by-step explanation:
Initially, the floor is (completely) covered with 64 white tiles.
Now we remove x white tiles, and we replace them with blue tiles.
Then if we removed x white tiles, now the number of white tiles is:
64 - x
And we know that after Rosario finishes the work, there are 40 white tiles left in the floor.
Then:
64 - x = 40
now we can solve this for x.
64 - 40 = x
24 = x
this means that 24 blue tiles were used.
Linear equation is the equation in which the highest power of the unknown variable is 1. Linear equations are used to solve the condition based problems. The number of the blue floor tiles is 24.
Given information-Rosario is working on an 8-foot-by- 8-foot floor.
The floor is covered with 64 white tiles.
Linear equation
Linear equation is the equation in which the highest power of the unknown variable is 1. Linear equations are used to solve the condition based problems.
As she replaces x tiles with blue tiles, therefore the number of the white tiles remain say y,
[tex]y=64-x[/tex] ......1
Suppose the above equation is equation number 1.
Now after she's finished the work, there are 40 white tiles left. This 40 tiles are replaced by the blue tiles. As we had supposed the number of reaming tiles is y and the value of remaining tiles is 40. Thus,
[tex]y=40[/tex]
Put this value of y in the equation 1. Thus,
[tex]40=64-x[/tex]
Solve for x, we get,
[tex]x=64-40\\ x=24[/tex]
Hence the number of the blue floor tiles is 24.

Lines p and q are perpendicular. If the slope of line p is 2, what is the slope of
line a?
Answers
Answer:
D. -½
Step-by-step explanation:
Since line p and q we perpendicular to each other, thus, the slope of line q will be the negative reciprocal of the slope of line p.
Given that line p has a slope of 2, therefore, the slope of line q will be the negative reciprocal of 2.
Negative reciprocal of 2 = -½.
Slope of line q = -½.

There are two squares.ONe has a side length of 12 inches and the other has a side length of 14 inches.What is he total area of both squares?
Answers
Answer:
340 in^2
Step-by-step explanation:
1. First square
A = l*w = 12^2 OR 12*12 = 144
2. Second square
A = l*w = 14^2 OR 14*14 = 196
3. Combined Area
144+196=340
The area of a square is found by squaring the side length, which is the same as multiplying two of the sides together.
Square 1: 12 x 12 = 144 square inches.
Square 2: 14 x 14 = 196 square inches.
Total area = 144 + 196 = 340 square inches.
