Answer:
The Length of <em>JK</em> is 10
Step-by-step explanation:
Because <<em>J </em>is congruent to <<em>L</em> we know that the triangle in question must be isosceles as in an isosceles triangle two angles opposite of each other are equal. (This is also true for equilateral triangles, however, in an equilateral triangle all sides must be congruent, so we can rule equilateral out as <em>LJ </em>is not congruent to <em>KL.) </em>This means that the triangle must be isosceles.
In an isosceles triangle the side opposite each other are congruent, and the angles opposite each other are congruent when split down the line of symmetry.
Therefor, the length of <em>JK </em>must be congruent to the length of <em>KL. </em>In other words if <em>JK </em>= 10, then <em>KL </em>must equal 10 as well.
Answer:
A is the correct answer
Step-by-step explanation:
As the question is asking what simple is the correct one and the lines sorry I forgot what the name of them is. Then lines make negatives positive it does not effect a positive number as the number is positive.

no
Answer:
72
Step-by-step explanation:
Use PEMDAS
Parentheses
Exponent
Multiplication and Division (if it contains both, just go from left to right)
Addition and Subtraction (if it contains both, just go from left to right)
8 + (5)(4) − (6 + 10/2) + 55
8 + 20 − (6 + 10/2) + 55
28 − (6 + 10/2) + 55
28 − (6 + 5) + 55
28 − 11 + 55
17 + 55
72
To solve it step by step with PEMDAS:
Solve within the parentheses
6 + 10/2
10/2 = 5
6 + 5 = 11
Multiply/Divide
(5)(4) = 20
Add/Subtract
8 + 20 - 11 + 55 = 72
72
