I need this answer pleaseee:(

Answer:

Given - A triangle PMQ

To find - Measure of Q and N

Solution -

In triangle PMQ

Angle p = 37°

Angle M = 78°

Using Angle sum property of triangle :

Sum of all angles of a triangle = 180°

Angle M + Angle p + Angle N = 180°

78 + 37 + N = 180°

115 + N = 180°

N = 180 - 115

N = 65°

In triangle PQR 

Angle p = 37°

Angle R = 65°

Using Angle sum property

Sum of all angles of a triangle = 180°

Angle p + Angle R + Angle Q = 180°

37 + 65 + Q = 180°

102 + Q = 180

Q = 180 - 120

Q = 60°

Consider parallelogram VWXY below.

olchik [2.2K]

note:Parallelogram WXYZ not VWXY & I will answer the questions in the image b'cos I don't get your question.

Answers:

a.(i.)Slope of line YZ = 4/5

(ii.)Line adjacent line YZ is line YX,slope of YX =5/4

b.(i.)Length of line YZ =√41 units

(ii.)Length of line YX =√41 units

c.WXYZ is a rhombus.

Step-by-step explanation:

a.Slope=gradient(m)=(y₂-y₁)/(x₂-x₁)

(i.)m of line YZ=(y₂-y₁)/(x₂-x₁) where Y(-6,-1) & Z(-1,3)

(I believe you know what the y₂,y₁,x₂ & x₁ stand for.)

So m=(y₂-y₁)/(x₂-x₁),=(3-(-1))/(-1-(-6) =(4)/(5)=4/5

∴m of line YZ is 4/5

(ii.)m of line YX=(y₂-y₁)/(x₂-x₁) where Y(-6,-1) & X(-2,4)

So m=(y₂-y₁)/(x₂-x₁),=(4-(-1))/(-2-(-6) =(5)/(4)=5/4=1.25

∴m of line YX is 5/4

b.(i.)To find the length of line YZ,we have to express it as column vector YZ.

Vector YZ=OZ-OY,Z-Y=(-1,3)-(-6,-1)=(5,4)

Length=√x² plus y²=√5² plus 4²=√25 plus 16=√41 units

∴The length of line YZ is √41 units.

(ii.)To find the length of line YX,we have to express it as column vector YZ.

Vector YX=OX-OY,X-Y=(-2,4)-(-6,-1)=(4,5)

Length=√x² plus y²=√4² plus 5²=√16 plus 25=√41 units

∴The length of line YX is √41 units.

c.WXYZ is a rhombus.

Alison set aside $55 each month to spend on books and cd .If she spends c dollar on cds given a month she may spend b dollar on

WINSTONCH [101]

For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25
