Answer:
trigonal bypyramidal
Step-by-step explanation:
It's difficult to explain without a drawing or a model, but it would basically arrange itself into two triangle based pyramids connected to each other at the base, which is trigonal bypyramidal.
Answer:

Step-by-step explanation:

Divide both sides by 12:

Simplify the fraction:

Find the greatest common factor of the numerator and denominator:

Factor out and cancel the greatest common factor:

Sum of complementary angles = 90
so
5x + 35 = 90
5x = 90 -35
5x = 55
x = 11
answer is A.
x = 11
