Answer:
Step-by-step explanation:
Given
The attached triangle
Solving (a) BA
Considering the tangent of angle C, we have:
This gives:
Make BA the subject
--- approximated
Solving (a) BC
Using Pythagoras theorem
Square root of both sides
The answer is The Multiplication or Division Principle of Equality. It states that if you multiply or divide both sides of an equation by an expression, the resulting the equation will be equivalent to the original equation.
14x = 56
x = 4 <-- Divide both sides by 14
So, x is equal to 4.<span />
Answer:
Step-by-step explanation:
10. To solve for this, use the formula: 180*(n-2)
So, 180(n-2) = 2,340
Once n is solved for, that is the number of sides
11. Use the formula:
[180*(n-2)]/n
(n represents the number of sides)
12. Think of the sum of all interior angles in a quadrilateral
Answer: 8 & 13
Step-by-step explanation:
13 squared is 169 and 8 squared is 64, and the difference of those two squares would be 169 - 64 = 105. Hope this helps!
