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.
Answer:
arc KLJ = 205°
Step-by-step explanation:
Recall: measure of arc equals measure of central angle
Therefore:
measure of arc LJ = 56°
measure of arc KL = 149°
arc LJ + arc KL = arc KLJ
Substitute
56° + 149° = arc KLJ
205 = arc KLJ
arc KLJ = 205°
Answer:
No, the radicands are not added.
Step-by-step explanation:
When adding or subtracting like radicals, we treat them as we treat algebraic expressions:
4 x + x - 2 x= 3 x
In the sense that we associate the "x" above with the radical expression. So for example:
The radicals remain the same, and we treat them as algebraic expressions, just combining adequately the multiplicative factors the radicals have.
Use the formula
1/3*pi*r^3*h=Volume
It is simple algebra
