D=360-20-25-80=235

x=360-235=125

Answer:

BDC + ABD +ACD + BAC = 360

80 + 20 + 25 + BDC = 360

BDC + 125 = 360

BDC = 360-125

BDC = 235

Now,

BDC + x = 360

235 + x= 360

x = 360-235

x = 125

A bicycle path divides a rectangular park. The path makes a 42° angle with the top border of the park, so mZ1 = 42°. What is m/2? How do you know?

Answers

Answer: 0.5 meters because m=meters and meters/2 = 0.5

The required measure of the angle m∠2 is 138°.

Given that,
A bicycle path divides a rectangular park. The path makes a 42° angle with the top border of the park, so mZ1 = 42°. What is m/2 is to be determined.

What is a rectangle?

The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.

Here,
According to the question,
Let the measure be x,
Now the bicycle path divides the rectangular park,
So,
m∠1 + m∠2 = 180
42 + x =180
x = 180 - 42
x = 138°

Thus, the required measure of the angle m∠2 is 138°.

Given: triangle NOP is similar to triangle WXY

We know that NOP has a base length of 4 while triangle WXY has a base length of 10

10 / 4 = 2.5

The scale factor = 2.5

We also know that all similar triangles have congruent angles

The measure of angle X on triangle WXY = 58 degrees because its corresponding angle on triangle NOP = 58 degrees.

We know that all the angles of a triangle add up to 180.

The measure of angle P for triangle NOP is:

180 - (49 + 58) = 73 degrees. This means that the measure of angle Y for triangle WXY is also 73 degrees.

We know that the scale factor = 2.5 so 12 / 2.5 = 4.8

NP / WY = 12 / 4.8 = 2.5

The length of WX = 6 * 2.5 = 15

The length of NP = WY / 2.5 = 12 / 2.5 = 4.8

The scale factor of triangle NOP to triangle WXY is 2/5 =0.4.

What are similar triangles?

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, ΔNOP∼ΔWXY

NO/WX =OP/XY =NP/WY

6/WX =4/10 =NP/12

a) The scale factor is 4/10 =2/5

b) m∠X=58

c) m∠Y=

m∠N+m∠O+m∠P

=49°+58°+m∠P=180°

107°+m∠P=180°

m∠P=73°

So, m∠Y=73°

d. 6/WX =4/10 =NP/12

4/10 =NP/12

2/5=NP/12

NP=24/5

NP=4.8

So, NP/WY =4.8/12

e) WX

6/WX =4/10

60=4WX

WX=60/4

WX=15

f) NP

4/10 =NP/12

2/5=NP/12

NP=24/5

NP=4.8

Therefore, the scale factor of triangle NOP to triangle WXY is 2/5 =0.4.

Twin brothers, Billy and Bobby, can mow their grandparent’s lawn together in 63 minutes. Billy could mow the lawn by himself in 25 minutes less time that it would take Bobby. How long would it take Bobby to mow the lawn by himself? I’ve tried multiple problems like this but I keep getting them wrong, please help.

Answers

Answer:

140 minutes

Step-by-step explanation:

this problem focuses on the combined work rate

both can finish the work under 63 minute

let bobby mow the lawn in x minute

Billy will then mow the lawn in x-25 minutes

Let the completed job = 1 (a mowed lawn)

we can now apply the combined work formula for the two boys as

[tex]\frac{63}{x}+\frac{63}{x-25}=1[/tex]

multiplying through by x(x-25 )we have

[tex]63(x-25)+63x= x(x-25)[/tex]

open bracket we have

[tex]63x-1575+63x= x^2-25x[/tex]

rearranging and collecting like terms we have

[tex]0=x^2-25x-63x-63x+1575 \\\\0=x^2-151x+1575 \\\\x^2-151x+1575=0[/tex]

we can now use the quadractic formula

[tex]x=\frac{-b\frac{+}{} \sqrt{b^2-4ac} }{2a}[/tex]

 

a= 1

b= -151

c= 1575

[tex]x=\frac{-(-151)\frac{+}{} \sqrt{151^2-4*1*1575} }{2*1}[/tex]

[tex]x=\frac{-(-151)\frac{+}{} \sqrt{22801-6300} }{2} \\\\x=\frac{-(-151)\frac{+}{} \sqrt{16501} }{2} \\\\x=\frac{-(-151)\frac{+}{} 128.45}{2} \\\\[/tex]

[tex]x=\frac{-(-151)+128.45}{2} \\\\\x=\frac{279.45}{2} \\\\x=139.72 \\\\\\x=\frac{-(-151)-128.45}{2}\\\\x=\frac{151-128.45}{2}\\\\x=\frac{22.55}{2}\\\\x=11.27[/tex]

the first answer x= 139.72 approximately 140 minutes mins is correct for  Bobby's time

let us check

[tex]\frac{63}{140}+\frac{63}{140-25}=1\\\\\\0.45+\frac{63}{115} =1\\\\0.45+0.5478=1\\0.997 =1[/tex]

we can see that the solution approximates to 1
