So, we know that a^2 + b^2 = c^2. Right? That is called the Pythagorean Theorem.
In this case. We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b. a & b are just the two legs of the right triangle.
So, if we say that 39 is a, 40 is b, and x is c. We can plug it into the Pythagorean Theorem.
39^2 + 40^2 = x^2
I'll let you take it from there.
Answer:
![\frac{(2)A}{h} =b](https://tex.z-dn.net/?f=%5Cfrac%7B%282%29A%7D%7Bh%7D%20%3Db)
b=0.00906m
Step-by-step explanation:
Hello! To solve this exercise we must remember that the area of any triangle is given by the following equation
![A=\frac{bh}{2}](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bbh%7D%7B2%7D)
where
A=area=32.5m^2
h=altitude=7172m
b=base
Now what we should do take the equation for the area of a rectangle and leave the base alone, remember that what we do on one side of the equation we must do on the other side to preserve equality
![A=\frac{bh}{2} \\\frac{2}{h} A=\frac{bh}{2} \frac{2}{h} \\](https://tex.z-dn.net/?f=A%3D%5Cfrac%7Bbh%7D%7B2%7D%20%5C%5C%5Cfrac%7B2%7D%7Bh%7D%20A%3D%5Cfrac%7Bbh%7D%7B2%7D%20%5Cfrac%7B2%7D%7Bh%7D%20%5C%5C)
![\frac{A(2)}{h} =b](https://tex.z-dn.net/?f=%5Cfrac%7BA%282%29%7D%7Bh%7D%20%3Db)
solving
![\frac{2(32.5)}{7172} =0.0090[tex]\frac{A(2)}{h} =b\\b=0.00906m](https://tex.z-dn.net/?f=%5Cfrac%7B2%2832.5%29%7D%7B7172%7D%20%3D0.0090%5Btex%5D%5Cfrac%7BA%282%29%7D%7Bh%7D%20%3Db%5C%5Cb%3D0.00906m)
Answer:
550km/h
Step-by-step explanation:
v (speed) = d/t
v = 1375/2.5
v =550
Answer:
supplementary angles
Step-by-step explanation:
they are on the same line, so they sum up to 180°
