Answer:
292 inches^2
Step-by-step explanation:
So to start off this is a picture of the fish tank.
Next we will find the area of the bottom and top rectangles.
The side lenghts for those two is 7 and 8.
So the area of one is 56 and the area of 2 is 112 inches^2.
Now we will find the area of the left and right rectangles.
The side lenghts are 6 and 8.
So the area of 2 is 96 inches^2.
Now for the front and back rectangles.
The side lenghts for those two are 6 and 7.
So the area of both is 84 inches^2.
So after adding all the areas up the surface area is 292 inches^2.
Answer:
1. yes, both triangles sides are congruent
2. yes, they have congruent sides and they have a congruent angle
3. yes, congruent sides and angle
4. yes, 2 congruent angles
5. no, only one congruent angle not enough proof
6. yes, 2 congruent angles
7. no, only one congruent angle not enough proof
8. no, only one congruent side

130+x-5+x-35+x+30+75=360
3x=360-195
3x=165
x=55
m (B)=55-5=50
