Explanation:
first find the slope m of the line passing through the
the 2 given points
to calculate the slope m use the
gradient formula

the equation of a line in
slope-intercept form
is.

where m is the slope and b the y-intercept

You can use the pythagorean theorem.

Now lets write out what we know.
Shorter leg = x
Longer Leg = x + 7
Hypotenuse = x - 7

Now solve for x

x = 28
Since you know x = 28, which is the shorter leg, you can solve for the rest by just plugging in 28 where x is located. For instance, longer let is x + 7 so
28 + 7 = 35
Step-by-step explanation:
I don't understand dis question
pls can u say more on it
it flies 1666.67 meters in 10 seconds.
Speed = 600km/h
1km = 1000m
1hour = 3600 sec
convert speed in km/h to m/s
600 x 1000/3600 = 6000/36 = 166.667 m/s
Now this speed is for per sec, in 10 sec = 166.667 x 10 = 1666.67m
Trapezoid= (base 1+base2)×height÷2
square, rectangle, rhombus, parrellogram, etc= base × height
triangles=base ×height÷2
hope this is what you were looking for if it's not in feet already you need the convert it
