Answer:
For the 1st one: 63
For the second one: 99
Step-by-step explanation:
This is because to find the perimeter, you have to do length+length+width+width=area
So you do 77+77+x+x=280, this should get you x=63
For the second one, to find area you do length×width=area
So you do 59×x=5841 and should get 99.

3. Suppose the radius of the larger circle is r. What is its diameter?
d2 =
R2
Answers
Answer:
2r
Step-by-step explanation:
You suppose that the radius of a larger circle = r
so diameter = r*2 = 2r
aint really sure tho
Answer:
2R
Step-by-step explanation:
The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.

Here are three intersecting lines. Write an equation that represents a relationship between these angles. Describe, in words, the process you would use to find .
Answers
Answer:
[tex]w = 52[/tex]
Step-by-step explanation:
Given
See attachment for intersecting lines
Required
Find w
Using the horizontal line as a point of reference, the blank angle between w and 76 equals w.
This is so because it corresponds to angle w, at the bottom of the horizontal line.
So, to find w, we make use of:
[tex]w + w + 76 = 180[/tex] --- angle on a straight line
Collect like terms
[tex]w + w = -76 + 180[/tex]
[tex]2w = 104[/tex]
Solve for w
[tex]w = \frac{104}{2}[/tex]
[tex]w = 52[/tex]

Answer:
92 is your answer
Step-by-step explanation:
we have
3x/4-1=x/2+7 side of square are equal
3x/4-x/2=7+1
(3x-2x)/4=8
x=8×4=32
length =3×32/4 -1=24-1=23
now
perimeter=4×length=4×23=92 units
Answer: The perimeter of the square is 92 units.
Step-by-step explanation:
All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :) Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.
3/4(32) - 1 = 23
1/2(32) + 7 = 23
After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!

A triangle has two angles that measure 45 degrees and 35 degrees. What is the
measurement of the third angle?
Answers
Well, we know that a triangle's angles add up to 180°, so 45 + 35 + x = 180, and x = 100.
The third angle is 100.
Answer:
The measurement of the third angle is 100 degrees.
Step-by-step explanation:
Just add 45 + 35 which equals to 80. Every triangle's angles equal to 180 degrees so subtract 80 from 180. That equals 100 degrees.
Equation: 45+35=80
180-80=100
Hope this helps! :)
What is m∠1? Help me, please
Answers
Answer:
∠1 = 72°
Step-by-step explanation:
exterior ∠ = the sum of two opposite(remote) interior ∠s
∠1 = 37° + 35°
=> ∠1 = 72°
Answer:
72 degrees.
Step-by-step explanation:
Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:
35+37=72
m<1 = 72 degrees

Can someone help me I’m stuck and I don’t get it
Answers
Answer:
The first one (highlighted one)
Step-by-step explanation:
The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.
