Answer:
(-7, 31)
Step-by-step explanation:
To solve this equation, simply plug in the numbers. For example, with -3 and -11, you simply plug them into the equation:
- -11 = -5 (-3) - 4
- After you solve this, you'll see the equation does not come out to -11; rather, it comes out to +11.
Repeat this with all equations, and you will see which are correct. Be careful, however, and remember which number goes into which value.
If the triangle has a angle of 90°, you can solved this exercise by applying the Pythagorean Theorem, which is:
h²=a²+b²
h=√(a²+b²)
h: It is the hypotenuse
(The opposite side of the right angle and the longest side of the triangle).
a and b: They are the legs
(The sides that form the right angle).
The result of h=√(a²+b²), should be 17.1 (The longest side given in the problem). So, let's substitute the values of the legs into the Pythagorean equation:
h=√(a²+b²)
h=√((9.2)²+(14.5)²)
h=17.1
Therefore, the answer is:
Yes, the given measures can be the lengths of the sides of a triangle.
PR would be 17.72 as the hypotenuse, according to the measurements, is 17.72
Let the larger number be w and the smaller number be k;
5w-11=3k
3k+16=4w
Reorganizing the equations;
5w-3k=11
4w-3k=16
Subtracting equation 2 from equation 1:
w=-5
Replacing value of w in equation 1;
5(-5)-11=3k
-25-11=3k
3k=-36
k=-12
The numbers are -5 and -12
