Find the value of x.
Do u know the total interior angle of a pentagon?>
Not really:/
Ok, so it's necessary that u know the total interior angle of the pentagon. So the first step is to find it. Use the formula \[{180(n-2)}\]Where n is the number of sides.
So, u have 5 sided figure. so what will be the value of "n" be?
Erm, I have no idea and I don't wanna guess.
Seems like they also, don't want to do any math?????
More like don't understand it.
How many sides is your figure? that is your n value, sub it into the formula he gave you and that will tell you how many degrees your figure is made up of
Ohhh thanks!:)
So n is 5, correct?
yes
add up all of your interior angles and set it equal to that number and solve for x
So substituted 180(n-2) is 180(5-2) which is 180(3) then 540?
yes set it equal to 540
So what does the formula look like now and what's my next step?
all up all the given interior angles here is a hint the little box represents a right angle and that is 90 degrees 90 + 112 + ..........finish=540 solve for x
Is it 90x or 112x?
really????
Name all of the angles (Hint: Look at the picture you posted) Start with 90 degrees
Is it 67.5 or 68?
what equation did you use? I am still waiting for you to tell me all of the angles listed on your picture.
Angles are 148,112, 2x+10 and 2x right? I'm so bad at this.
but you forgot 90 degrees that is what the little box means
90 + 112 + 148+ 2x+10+2x=540 solve for x
Ah yes, 90! Forgot that!
ok solve for x
x=13.5 ish
Can you help me with one mor question?!
there is no ish in mathematics 90 + 112 + 148 + 2x+10+ 2x=540 360 + 4x=540 -360 -360 4x=180 divide both sides by 4 x=45
well post it, if I can help I will
Give the name that best describes the parallelogram and find the measures of the numbered angles.
Ahh, I added the formula wrong.
ok angles 1, 3 are the same value angles 2, 4 are the same value by the alternate interior angles triangles equal up to 180 degrees 180-116=64 degrees
2 and 3 add up to 64 degrees
Triangle is an isoceles and those angles are equal ie 2 and 3 are equal so what do you think the answer is
64
angle 2 and 3 are the same value they both add up to 64
then 128
oh wait lol, 32
I was beginning to worry yes 32
Yay! Thank you so much!:)
Anytime :)
