Which of the pairs of angles are complementary? ∠apb and ∠zpb ∠apz and ∠bpz ∠apw and ∠zpw ∠wpz and ∠bpz

∠APW and ∠ZPW

Step-by-step explanation:

Pair of complementary angles : A pair of angles whose sum is 90° is said to be the pair of complementary angles.

Option 1 : ∠APB and ∠ZPB

Since APB is straight line

So, ∠APB = 180°

∠ZPB = 90°(Given)

So, ∠APB +∠ZPB=180°+ 90°= 270°

Since the sum of angles is not 90°.

Thus Option 1 is not a pair of complementary angles.

Option 2: ∠APZ and ∠BPZ

∠APZ = 90°

∠BPZ = 90°

So, ∠APZ +∠BPZ =90°+90° =180°

Since the sum of angles is not 90°.

Thus Option 2 is not a pair of complementary angles.

Option 3 : ∠APW and ∠ZPW

∠APW+∠ZPW=∠APZ

∠APZ =90°(Given)

So,∠APW+∠ZPW=90°

Since the sum of angles is 90°.

Thus Option 3 is  a pair of complementary angles.

Option 4: ∠WPZ and ∠BPZ

∠WPZ + ∠BPZ =  ∠WPZ + 90°

Since the sum of angles must be greater than 90°.

Thus Option 4 is not a pair of complementary angles.

Hence ∠APW and ∠ZPW are the pair of complementary angles.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

idk the answer i want to say 10 but then it would be equal so try 9 but then yeah so yeah we love edgen
