Answer:

3.5 km

Step-by-step explanation:

For this question, we must use the pythagorean theorem: a^{2}+b^{2}=c^{2}

C is the hypotenuse which is 4 km. We can set A as 2 km. We would plug in the values to get 2^{2}+ b^{2}=4^{2}.

Then we must isolate the b value. We get = -. This then simplifies down to  =12. Then we square root both sides to get b=3.5

Answer:

sqrt{12}

Step-by-step explanation:

We can find how long the missing side is with the help of Pythagoras and his theorem.

a² = c² - b²

a² = 16 - 4

a² = 12

a = sqrt{12}

Find the values of x and y
qaws [65]

Answer:

y=30

x=60

Step-by-step explanation:

The triangle has all sides equal therefore all the angles are equal.

For all the angles to be equal and add up to 180 (sum of angles in a triangle is 180), each angle has to be 60.

Therefore y=90-60

=30

x=180-(30+90)

=60

makkiz [27]

Answer:

A = 2,384.1708

A = P(1  + rt)

P = 942.36

r = 12.75%

t = 12 months

A = 942.36(1 + 12.75/100(12))

A = 942.36(2.53)

A = 2,384.1708
