In a 45 45 90 triangle, the length of each leg = hypotenuse / sq root (2)
each leg = (24 / 1.4142)
each leg = 16.971
Area of a triangle = (base * altitude) / 2
Area of a triangle = (16.971 * 16.971) / 2
Area = 144.007
Answer:
x = 23
Obtuse scalane triangle
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
110+35+x+12 = 180
157 + x = 180 subtract x from both sides
x = 23
The given triangle is an obtuse scalane because it has no eqaual side lengths or angles measurment.
1. - Since a cube is all the same lengths on all sides you would want to find the area of one of the sides. You would do this by multiplying 3.8 by 3.8.
3.8*3.8=14.44
Since you have six faces on a cube you want to multiply this by 6.
14.44*6=86.64
So your answer for 1. is 86.64 in^2 of glass
3. Same thing as number one. Find the face of one side:
1 1/3*1 1/3 is about 1.7777
Multiply this by the six faces.
1.7777*6 is about 10.66666
So your answer for 3. is about 10.666 (repeating) in^2
4. For this one, you want to follow the surface area formula for a cylinder. Which is - A=2πrh+2πr^2
When you put all your numbers in it would look like this:
2*3.14*2*22+2*3.14*2^2
Once you do that equation you will get 301.44
So that should be your answer 301.44 cm^2
Hope this helps!
