Answer:
230 cm^2
Step-by-step explanation:
The area of each parallelogram face is ...
A = bh = (8 cm)(3 cm) = 24 cm^2
The area of the two rectangular faces shown is ...
A = (area of top face) + (area of right side face)
A = (8 cm)(7 cm) +(5 cm)(7 cm) = 91 cm^2
The three faces we have figured the area of are half the total area, since there are three more faces exactly the same size. Then the total area of the figure is ...
total surface area = 2(24 cm^2 +91 cm^2) = 230 cm^2
_____
Of course, the area of a rectangle is given by A=L·W, where L and W represent the length and width of the rectangle.
Answer:
Triangle 1: x = 80 degrees, acute
Triangle 2: x = 10 degrees, right
Step-by-step explanation:
Triangle 1:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation:
![60 + 40 +x = 180](https://tex.z-dn.net/?f=60%20%2B%2040%20%2Bx%20%3D%20180)
Solve for x:
![100 + x = 180\\x = 80](https://tex.z-dn.net/?f=100%20%2B%20x%20%3D%20180%5C%5Cx%20%3D%2080)
So, x = 80 degrees
Because all the angles are less than 90 degrees, this is an acute triangle.
Triangle 2:
By the Sum of Interior Angles Theorem, all the angles inside the triangle adds up to 180 degrees. So, set up this equation (with the right angle given):
![3x + 60 + 90 = 180](https://tex.z-dn.net/?f=3x%20%2B%2060%20%2B%2090%20%3D%20180)
Solve for x:
![3x + 150 = 180\\3x = 30\\x = 10](https://tex.z-dn.net/?f=3x%20%2B%20150%20%3D%20180%5C%5C3x%20%3D%2030%5C%5Cx%20%3D%2010)
So, x = 10 degrees
Because there is an angle measuring 90 degrees, this is a right triangle.
Answer: Y= 2 X=1
Step-by-step explanation:
2x+y=4 4x+2y=8
2x =/2 2y= /2
y=2 4x=4
/4= /4
X= 1
