Question 14 of 42 What is the area of the obtuse triangle below?

A. 90 sq. units
B. 45 sq. units
C. 15 sq. units
D. 21 sq. units

90

Explanation:

the answer is 90 because to find the area of a triangle you multiply base times height so 15×6 which gives you 90

because the two particles have an equal charge, the charges will cancel out and give the atom an overall charge of 0. so, if at atom has 35 protons in the nucleus, we could expect it to have 35 electrons orbiting that nucleus.
