Is 0 because it's to the power of zero
Since 2 sides of the triangle are the same, it's an isosceles triangle.
That would also mean that the two angles are the same; 70 and 70.
A triangle has 180 degrees total.
70 + 70 + x = 180
x = 40
Answer:
Step-by-step explanation:
y = 3x - 5
6x + 3y = 15
Substitute the first equation into the second
6x + 3(3x - 5) = 15
6x + 9x - 15 = 15
15x = 30
x = 2
Then use the answer in the first equation and solve
y = 3(2) - 5
y = 6 - 5
y = 1
The Surface area of a cuboid with length 10 cm breadth 10 cm and height 9 cm is 560 cm².
<h3>What is the surface area?</h3><h3>A cuboid is a three-dimensional figure bounded by six rectangular planes, having a different magnitude of length, width and height. If you look around and you can see a box, brick or anything in the shape of a rectangle, it could be cuboid. </h3>
Here, length of cuboid is 10 cm
breadth of cuboid is 10 cm
and height of cuboid is 9 cm
Surface Area of Cuboid = 2 (lb + bh + lh)
= 2 (10X10 + 10X9 + 10X9)
= 2 (100 + 90 + 90)
= 2 X 280
Surface Area of Cuboid = 560 cm²
Thus, the Surface area of a cuboid with length 10 cm breadth 10 cm and height 9 cm is 560 cm².
