First, let's turn the fractions into decimal form so you can see the answer, more clearly.
2
= 2.25
2.4 = 2.4
2
= 2.125
Now, after looking at the decimals, we can see which decimals are the biggest. They would order, from least to greatest, like this.
1) 2.4
2) 2.25
3) 2.125

Answer:
62
Step-by-step explanation:
Since you know that JK + KL = JL, this would be:
27 + 3x - 1 = 5x + 2
Now, solve this equation:
combine like terms first
subtract 3x from both sides
subtract 2 from both sides
divide both sides by 2
Since you want to find JL and JL = 5x + 2, plug x = 12 into that equation.
Answer:
(1) Option A is correct , The measure of angle A = 26°
(2) Option D is correct, The measure of angle B =70°
Step-by-step explanation:
(1)
In a right angle triangle figure-1 ,
* Hypotenuse(H) is always opposite the right angle and it is always the longest side of the triangle.
* Adjacent side (B) is the non-hypotenuse side that is next to a given angle A.
* Opposite side(P) is across from a given angle A.
To find the Angle A we use the Cosine ratio:
Cosine ratio states that the ratio of the adjacent side of a right triangle to the hypotenuse.
By definition of cosine ratio we have;
....[1]
In the figure - 1 we have B = 18 in and H = 20 in
substitute these in [1] to find angle A
or
⇒
therefore, the measure of angle A is,
(2)P
In figure -2
Find the measure of angle B.
First find the side BC, using Pythagoras theorem;
Pythagoras theorem states that in the right angle triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
Apply Pythagoras theorem in rt. angle ABC;
Substitute the values of AB = 5.1 cm and AC =4.8 cm to solve for BC
Simplify:
or
Now, find the angle B, using tangent ratio;
Tangent ratio states that the ratio of the Opposite side of a right triangle to the adjacent side.
Therefore, the measure of angle B is; .
