The length of side "f" would be about 9.95.

Using Pythagorean Theorem, you have the hypotenuse or side "c" (18) which is longest side. You also have side "b" (15).
Since the equation is "a^2 + b^2 = c^2”, fill in for "b" and "c" giving "a^2 + 15^2 = 18^2"
Solve for "a". Square each known value, leaving "a^2 + 225 = 324". Subtract 225 from each side, leaving "a^2 = 99" then use the square root on each side. Thus getting "a = 9.94987..., which rounded up is 9.95.

I hope this helps!

I am pretty sure the answer is 10. Someone correct me if I'm wrong
$10 {}^{2} + 15 {}^{2} = 18 {}^{2} \\ 100 + 225 = 325 \\ \sqrt{325} = 18$

Answer:

x = 30
y = 105
z = 75

Step-by-step explanation:

You know the linear pair z° and 105° are supplementary angles, so ...

z = 180 -105 = 75

The other base angle of the isosceles triangle has the same measure, 75°. __

Then x can be found either from the sum of interior angles of the triangle, or from the relation of 105° to the "remote interior angles". The first relation gives ...

75° +75° +x° = 180° ⇒ x = 180 -150 = 30

The second relation gives ...

75° +x° = 105° ⇒ x = 105 -75 = 30

y° is supplementary to the left-side base angle, so is ...

y = 180 -75 = 105

Of course, you could also figure y from the symmetry of the figure.

The values of x, y, z are 30, 105, 75, respectively.

Answer:

$area = 0.5 \times height \times width \\ = 0.5 \times (x + 2) \times (x +2 - 7) = 4 \\ 4 \div 0.5 = (x + 2)(x - 5) = 8 \\ {x}^{2} - 3x - 10 = 8 \\ {x}^{2} - 3x - 18 = 0 \\ (x - 6)(x + 3) = 0 \\ x = - 3 \\ x = 6$

Step-by-step explanation:

Remember: Coplanar definition: In the same plane.

Here, we can see that points G, N, and M make up the intersection of plane K and plane L, so that means our answers are: G, N, and M because we were looking forth e points that are on planes K and L. The other points are not the answer because they are either on only one of the planes or not on any of them at all.

I hope this helps! :)
