Answer:
AC = 
units²
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse AC is equal to the sum of the squares on the other 2 sides, that is
AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( take square root of both sides )
AC = ≈ 9.43 ( to 2 dec. places )
Your answer is 5.
On the first triangle ABC, the answers are all divided by 7, to the triangle DEF. So 35/7 is 5. Hope this helps.
Simplify:
3(x - 1) = 8x -3
Expand:
3x - 3 = 8x - 3
Cancel -3:
3x = 8x
Move all terms to one side:
3x - 8x = 0
Simplify 3x - 8 to -5x
-5x = 0
Divide both sides by -5:
x = 0
You have to add more there is no context here, apologies but try to make another question with maybe a picture and more text?
The corollary comes out through expression is m∡JXN = m∡MXK this
are opposite angles because line JK and Mn intersect each other .
<h3>
What is angle?</h3>
The angle can be defined as the one line inclined over other line.
As per the question,
Line MN and JK intersect each other and XY is the angle bisector.
so,
∡MXY = ∡KXY
∡KXY = ∡NXY
∡JXM = ∡NXK
Therefore, m∡JXN = m∡MXK also equal which is opposite angles.
