Answer:

first triangle (to left) b=8, second one c=17

Step-by-step explanation:

for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.

A^2   +  B^2  = C^2

^              ^          ^

^              ^         Hypotenuse

^        second side

first side

Substitute:

5^2 + b^2 = 9^2

SImplify:

25+b^2 = 81

Reduce:

b^2 = 64

Simplify:

b=8

In the second triangle, we are given 2 sides.

Let's do the same thing we did in the first one.

Givens:

A = 8

B = 15

Find:

C

Substitute:

8^2 + 15^2 = c^2

Simplify

64 + 225 = c^2

Reduce:

289 = c^2

Let's now square root both sides

square root of 289 is 17

so we are left with this:

c=17

Phew, you did it!

Hope this helped :))

Triangle JKL is transformed using the rule . Point K of the pre-image is at (4, 7). What are the coordinates of point K" on the
Zanzabum

Answer:

Option C.

Step-by-step explanation:

Consider the complete question is "Triangle JKL is transformed using the rule R(O,90^\circ)\circ r_{y=-x}(x,y). Point K of the pre-image is at (4, 7). What are the coordinates of point K'' on the final image?".

According to r_{y=-x}(x,y), we get

(x,y)\rightarrow (-y,-x)

According to R(O,90^\circ), we get

(x,y)\rightarrow (-y,x)

The rule R(O,90^\circ)\circ r_{y=-x}(x,y) means first reflection and then rotation.

We need to find the image of K(4,7).

After reflection, we get

K(4,7)\rightarrow K'(-7,-4)

After rotation, we get

K'(-7,-4)\rightarrow K''(4,-7)

Therefore, the correct option is C.
