These are what I call the Two Tired Triangles of Trig, 30/60/90 and 45/45/90. If you learn these cold now you'll save yourself some hassle down the road. These are generally the only right triangles teachers use when they want 'exact' answers.
Here are the facts to remember:
The ratio of the sides of the 45/45/90 triangle are 1:1:√2
The ratio of the sides of the 30/60/90 triangle are 1:√3:2, with the smallest opposite the 30 degree angle.
OK, let's fill in the angles first. Where we have a right triangle with 30/60/90 we fill in the missing one. For the half squares, the acute angles are 45 degrees.
For the lengths we apply the ratios. Hypotenuse of 45 degree right triangle is 4, so sides are 4/√2 = 2√2. When that's opposite 30 degrees, the other two sides are 2√2×√3 = 2√6 and 2×2√2=4√2.
2√6 is one side of a square, so all sides. The diagonal is 2√6×√2=2√12=4√3.
Half the square side is the smallest leg of a 30/60/90, so √6, with other leg √6×√3=√18=3√2 and hypotenuse 2√6.
The solution of the given equation w.r.t m is m = 3 ,i.e., option A
<h3>What are Algebraic equations?</h3>With one exception, algebraic equations are essentially algebraic expressions.
An = sign is required in all algebraic equations.
No matter what kind of equation it is, all equations use the = sign.
The next topic is algebraic expression, which lacks the operators =,,, >, and.
To put it simply, there is no comparison between two terms in an algebraic statement.
Algebraic expressions frequently use terms like polynomial and square root.
So you now recognize the distinction between the two?
1) An algebraic equation has the symbol =, and 2) an algebraic expression lacks any comparison symbols (such as > and =).
As per the question:
55/9 + 10/3 = 85/3
(55m+30m)/9 = 85/3
85m/9 = 85/3
85m = (85*9)/3
85m = 85*3
m = (85*3)/85
∴ m = 3
