Answer:
x+18=90-x
use this equation and solve
2x=72
x=36
36+18=54
90-54=36
54 degrees and 36 degrees
The solution is, the measure of an angle and its complement are, 54 degrees and 36 degrees.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
let, one angle = x
x+18=90-x
use this equation and solve
2x=72
x=36
so, we get,
36+18=54
90-54=36
Hence, The solution is, the measure of an angle and its complement are, 54 degrees and 36 degrees.

4 minutes 53 seconds to seconds
Answer:
It's 293 seconds
Step-by-step explanation:
Answer:
293 seconds
Step-by-step explanation:
There are 60 seconds in a minute so 4x60=?
you know 4x6=24 so just take away the zero then add it back so it would be 240 then you just add 53 so, 240+53= 293 seconds and that's the answer.
Which equation is true?

what is the density of a pine log if the weight is 42.63 lbs, radius 5 in, length 30in
Answer:
Step-by-step explanation:
density is weight divided by volume. And the volume of a log is like a cylinder.
V=hpi(r^2) in this case
V=25(30)pi=750pi so
d=(42.63)/(750pi)
d=0.018 lb/in^3
Q2.
(a) Expand and simplify (m-8)(m + 5)
We can split the m-8 into 2 terms m and -8 each multiplying the next ( ) like this...
m(m+5)-8(m+5)
Now we expand
m^2+5m-8m-40
then simplify!
m^2-3m-40
Done!

If A = 56, then find c
Answer:
Since A= 56 then B=56 so A+B=112
The whole tringle must be 180 degrees
So 180-112=68
SO C=68

Solve for value the two angles in the triangle and classify the triangle using the sides and angles
Step-by-step explanation:
x + 15 +2x + 66 = 180
3x + 81 = 180
3x = 99
x = 99/3 = 33
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you.
Answer:
The angles are 66, 66, and 48 degrees
The triangle is isosceles because 2 angles are equal, thus two leg lengths are equal
Step-by-step explanation:
the sum of all three angles in a triangle = 180 degrees
66 + 2x + (x+15) = 180
simplify
66 +3x + 15 = 180
reduce
81 + 3x = 180
subtract 81 from each side
81 - 81 + 3x = 180 - 81
3x = 99
divide both sides by 3
3x/3 = 99/3
x = 33

The sum of 2 of the exterior angles of a triangle is 222 degrees. What is the measure of the third exterior angle?
Answer:
Exterior angles always add up to 360 degrees, therfore 360 - 222 = 138
Step-by-step explanation:
360 - 222 = 138
the answer to your question is 138degrees.
For any shape the exterior angles will always add up to 260 degrees.
Hope this helps in the future!
Answer:
360 - 222 = 138
the answer to your question is 138degrees.
For any shape the exterior angles will always add up to 260 degrees.

2. The lengths of the sides of a triangle are 4cm, 5cm and 6cm. Find, in degrees to one decimal
place, the size of the largest angle of the triangle.
Answer:
82.8 degrees.
Step-by-step explanation:
The largest angle is opposite the longest side.
So we find the angle opposite the 6cm line using The Cosine Rule:
6^2 = 4^2 + 5^2 - 2.4.5 cos A
cos A = (6^2 - 4^2 - 5^2) / (-2*4*5)
= -5/ -40
= 0.125.
So m angle A = 82.819 degrees.

For all parts of this question, use the function y + 2 = 3(x + 4)
Part A: Complete the x-y table:
i would start by simplifying the equation to get y by itself, you don't need to do this, but it makes it a little easier
y + 2 = 3 ( x + 4) distribute the 3 through the parenthesis
y + 2 = 3x + 12. subtract 2 from both sides
y = 3x +10
now to fill in the chart simply plug in the value of x to see what value of y it produces
y = 3(-2) +10
y = -6+10
y = 4
(-2,4)
y = 3(0) + 10
y = 0 + 10
y = 10
(0,10)
y = 3(2)+10
y = 6 + 10
y = 16
(2,16)
y = 3(4) + 10
y = 12 + 10
y = 22
(4,22)

So you would compare 14.16 to 14.60
Solve for x. Round to the nearest tenth as needed
Step-by-step explanation:
by Pythagoras :
H²= B²+ P²
(7+x)²= x²+ 9²
49 + 14x + x² = x²+81
14x = x² -x²+81 - 49
14x = 32
x = 32/14 = 16/7 = 2.28 cm = 2.30 cm

What are the coordinates of the image after a dilation
with the center at the origin and a scale factor of 2?
(0, 0) (10, 0) (10,4) (0, 4)
(-2.2) (8, 2) (8.-2) (-2,-2)
(1, 1) (6, 1) (6, 3) (1, 3)
(0, 0) (0, 2) (5.0) (5,2)
Explanation:
The scale factor 2 means we multiply the coordinates of every original point by 2. A point like (-1,1) moves to (-2,2) after doing so
As another example, (4,1) moves to (8,2) after multiplying both coordinates by 2.
