Answer:

1a. x + 74.5= 90

subtract both sides by 74.5

x= 15.5° the results

2a. Set up the given

x + 180=180

subtract both sides by 180

x = 0 is the results

1/2 = 0.5

74 & 1/2 = 74 + 1/2 = 74 + 0.5 = 74.5

The complement to this angle is 90 minus the angle, so,

complement = 90 - angle

complement = 90 - 74.5

complement = 15.5

Convert this to a mixed number

15.5 = 15 + 0.5 = 15 + 1/2 = 15 & 1/2

If the given angle is 74 & 1/2 degrees, then the complement is 15 & 1/2 degrees

<h3>Answer: 15 & 1/2 degrees</h3>

==========================================

180 is the given angle. The supplement, let's call it x, will add to the given angle to get 180.

x+180 = 180

x+180-180 = 180-180

x = 0

So if we add 0 to the given angle 180, we get the result 180

<h3>Answer: 0 degrees</h3>

PY=2, HP=3, find HY Geometry

klemol [59]

Answer:

$HY=\sqrt{5}\ units$

Step-by-step explanation:

we know that

The triangle HPY is a right triangle (because the angle ∠HYP is a right angle)

Applying the Pythagorean Theorem

$HP^2=HY^2+PY^2$

substitute the given values

$3^2=HY^2+2^2$

Solve for HY

$9=HY^2+4$

$HY^2=9-4$

$HY^2=5$

$HY=\sqrt{5}\ units$

If (a+10) and (a+20)are supplementary angles,find them

motikmotik

Given:

(a+10) and (a+20) are supplementary

To find:

Each angle

Steps:

if 2 angles are supplementary that means they add up to 180°

(a + 10) + (a + 20) = 180

a + 10 + a + 20 = 180

2a + 30 = 180

2a = 180 - 30

2a = 150

a = 150/2

a = 75°

Now let's find value of each angle,

a + 10 = 75 + 10

= 85°

a + 20 = 75 + 20

= 95°

Therefore, the value of each angle is 85° and 95° respectively

Happy to help :)

I need help with this

yawa3891 [41]

Answer:

Step-by-step explanation:

In the graph given, we can expect the x axis to be horizontal and the y axis to be vertical. This means that the arm span represents y and the height represents x.

Therefore, if a girl on her team is 63 inches tall, we can say that y=x+2, and since height is x, y = 63 + 2 = 65

The vertices of a rectangle in the standard (x,y) coordinate plane are (0,0), (0,4), (7,0), and (7,4). If a line through (2,2) p

Hatshy [7]

Answer:

slope =0

Step-by-step explanation:

Given that the vertices of a rectangle in the standard (x,y) coordinate plane are (0,0), (0,4), (7,0), and (7,4).

The rectangle has length = 7 and width =4

We know rectangle has two lines of symmetry which are i) vertical line through mid point ii) Horizontal line through mid point

Since the line passes through (2,2) we have the line as middle line.

Hence the required line is $y =2$

Slope of the line =0
