Determine the length of the leg of a 45o – 45o – 90o triangle with a hypotenuse length of 15 inches. ( ANSWER NEEDS TO BE IN RED

SIZIF [17.4K]

Answer:

The lenghts of both legs: $\frac{15\sqrt{2}}{2}\ inches$

Step-by-step explanation:

By definition, when a triangle has angles that measures 45°, 45° and 90°, its legs are congruent.

Then, knowing the lenght of the hypotenuse, we can find the lenght (in inches) of any leg of the given triangle by applying the Trigonometric Identity $sin\alpha=\frac{opposite}{hypotenuse}$ :

$sin(45\°)=\frac{leg}{15}\\\\leg=\frac{15}{\sqrt{2}}$

Finally, simplifying, we get:

$leg=\frac{15(\sqrt{2})}{(\sqrt{2})(\sqrt{2})}=\frac{15\sqrt{2}}{2}$

The sum of 237 and six times the opposite of a number is 405. What is the number?

IgorC [24]

The number is 28.

The equation would be:

237 + 6(x) = 405

The problem states that 6 times the opposite of a number, however, since the number sign was not given, we do not know whether it is in a positive or negative form. So we leave it as only x.

237 + 6x = 405
6x = 405 - 237
6x = 168
6x / 6 = 168 / 6
x = 28

To check:

237 + 6 (28) = 405
237 + 168 = 405
405 = 405

50 pounds to 35 pounds percent change

lakkis [162]

So change from 50 to 35
first find change
50-35=15
50=100%
15=x%
percent means parts out of 100

15 out of 50=x/100
15/50=x/100
30/100=x/100
30=x
the answer is 30% change
