The shape is a rectangle, will you please help me find the angle measures of 1,2 and 3?
Ulleksa [173]

Answer:

  ∠1 = ∠3 = 54°; ∠2 = 36°

Step-by-step explanation:

Each of the triangles is isosceles. Triangles opposite each other are congruent, so ∠2 is congruent to 36°.

∠2 and ∠3 are complementary, so ∠3 is 54°. Since ∠3 is congruent to ∠1, it, too, is 54°.

A dog walker charges a flat rate of $6 per walk plus an hourly rate of $30. How much does the dog walker charge for a 45 minute
zvonat [6]

Step 1

<u>Find the equation in function notation</u>

Let

h-------> the number of hours

y-------> the function for the walker fee in dollars

we know that

the hourly rate is 30\frac{\$}{hour}

y=6+30h

in this linear equation

the independent variable is the variable h

the dependent variable is the variable y

<u>Convert to function notation</u>

Let

f(h)=y

f(h)=6+30h

Step 2

Find how much does the dog walker charge for a 45 minute walk

Convert the time in hours

1\ hour=60\ minutes

45\ minutes=45/60=0.75\ hours

substitute in the equation

For h=0.75\ hours

f(0.75)=6+30*(0.75)=\$28.5

therefore

<u>the answer is</u>

the dog walker charge for a 45 minute walk \$28.5

<u>Statements</u>

Step 3

<u>The dependent variable is the number of hours true or false</u>

The statement is false,

because the independent variable is the number of hours and the dependent variable is the walker fee in dollars

Step 4

<u>The function for the walker fee is f(h)= 30h+6 true or false</u>

The statement is True --------> see the Step 1

Step 5

<u>The dog walker charges $22.5 for a 45 min walk true or false</u>

The statement is False

Because the dog walker charges for a 45 minute walk \$28.5

Find x !!?????!!!????????????
mars1129 [50]

Answer:

x = 15

Step-by-step explanation:

Given

See attachment

Required

Find x

The figure in the attachment is a quadrilateral and the angles in a quadrilateral add up to 360.

So, we have:

90 + 6x + 5+ 10x - 40 + 4x + 5 = 360

Collect like terms

6x + 10x + 4x = 360 - 90 - 5 + 40 - 5

20x = 300

Divide both sides by 20

x = 15

Hence, the value of x is 15
