Two right triangles are congruent. find the value of x. right triangle with angle of 33 degrees, right triangle with angle of 9 x minus 15 degrees select one: a. 5 b. 6 c. 8 d. 12

Given that the two right triangles are congruent, there are two possibilities.

9x - 15 is equal to the angle 33°  or 9x - 15 is equal to the other angle of the first triangle.

Let's probe with the first option:

9x - 15 = 33 => 9x = 33 + 15 = 48

=> x = 48 / 9 = 5,33, which is no in the list of options.

Now, let's probe the second option.

The other angle of the first right triangle is 90° - 33° = 57°

Then, 9x - 15 = 57

=> 9x = 57 + 15 = 72

=> x = 72 / 9 = 8

Which is the option c. 8.

So, I am sure that if you have a figure it will be compatible with that answer, else yet the procedure to find the answer is what I have used here.

option c. 8
