Find the value of x in the triangle

Option D

Step-by-step explanation:

Use the Pythagorean theorem to solve this question

a2+b2=c2

c2 is always the hypotenuse, which is what we have to solve.

3^2+ 5^2=

9+25=34

Now we have to square 34 and there is our answer

√34

Step-by-step explanation:

By pythagoras theorem:

x² = 5² + 3²

x² = 25 + 9

x² = 34

x = √34

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
