Answer:
Triangle 1 -
(if they want simplest radical form) or 5.4 (if they want to the nearest tenth)
Triangle 2- i couldnt figure this one out- may not be true
Pythagorean Theorem is... C) true for all right triangles
Step-by-step explanation:
Answer:
Line A
Step-by-step explanation:
A line of symmetry is a line that divides a shape into exactly two equal halves.
A triangle is a polygon with three sides and three angles. A scalene triangle has no lines of symmetry, an isosceles triangle has more than one line of symmetry while an equilateral triangle has three lines of symmetry.
From the diagram we can see that line A divides the figure into two equal halves, hence line A is the line of symmetry.
As an improper fraction, the simplified answer would be 9/7 after you divide both top and bottom by 10
------------------------
If you need a mixed number, then 9/7 converts to 1 & 2/7 because
9/7 = 1 remainder 2
If you had 9 cookies and 7 friends, then each friend gets 1 whole cookie, and there will be 2 left over.
