Answer:
(11+-3)(1/2)
Step-by-step explanation:
To define a line segement you need 2 points (any 2 points because as long as you can draw a line between them) and then you must use capital block letters with a line on top for example if you have point A, and point B you wwoukd define it as AB with a line on top. hope this helps ;p
Answer:
Step-by-step explanation:
14x17x10=2380
10x10x10=1000
2380+1000=3380
v=3380
Answer:
253cm²
Step-by-step explanation:
Area of the trapezoid = 1/2(b1+b2)*h
Given
h = 22cm
b1 = 10.5cm
b2 = 12.5cm
Substitute
Area of the trapezoid = 1/2(10.5+12.5)*22
Area of the trapezoid = 1/2(23)*22
Area of the trapezoid =11*23
Area of the trapezoid = 253cm²
Hence the area of the trapezoid is 253cm²
If the hypotenuse is 58cm, and one of the others legs is 42cm the answer would be 40cm
Explanation:
Here you have to use the formula
![{a}^{2} + {b}^{2} = {c}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%2B%20%7Bb%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D)
Then you have to pose the formula in terms of one of the legs, so:
![{a}^{2} = {c}^{2} - {b}^{2}](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%3D%20%7Bc%7D%5E%7B2%7D%20-%20%7Bb%7D%5E%7B2%7D%20)
![a = \sqrt{ {c}^{2} - {b}^{2}}](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B%20%7Bc%7D%5E%7B2%7D%20-%20%7Bb%7D%5E%7B2%7D%7D)
So when you change the letter for numbers you have that:
![a = \sqrt{ {58}^{2} - {42}^{2} }](https://tex.z-dn.net/?f=a%20%3D%20%5Csqrt%7B%20%7B58%7D%5E%7B2%7D%20-%20%7B42%7D%5E%7B2%7D%20%7D)
a=40
