Answer:
It's a right triangle.
Step-by-step explanation:
△ABC with m∠A=30° , m∠B=60° , and m∠C=90°
It's a right triangle.
<u>Answer:</u>
The element is Chromium.
<u>Explanation:</u>
The atom has 24 protons and 12 neutrons.
We know that Cr has 24 number of protons, to the Chemical is Cr (Chromium)
Again, we know that the atomic number is the number of protons and the atomic mass is the sum of proton and neutron.
So, the atomic number is 24 and the atomic mass is (24+12)= 36
Therefore, the symbol is 
Answer:
y = 12/5x + 22
Step-by-step explanation:
First, let's find the slope of the AB line.
y2 - y1 / x2 - x1
3 - 8 / 2 - (-10)
-5 / 12
= -5/12
When a line is perpendicular to something, the slope becomes the opposite.
y = 12/5x + b
10 = 12/5(-5) + b
10 = -12 + b
22 = b
The approx. square root of 62 is 8 because 8^2 is 64
