Answer:
Photo 1: (a) C
(b) A
(c) D
Photo 2: 12.0416cm
Photo 3: 15.5242cm
Step-by-step explanation:
Photo 1: (a) 6×4=24
(b) 6(5)+6=36
(c) 6×6=36
Photo 2: Using Pythagoras' Theorem,
Unknown side length= square root symbol [(8×8)+(9×9)]
= 12.0416cm (6sf)
Photo 3: Using Pythagoras' Theorem,
AC= square root symbol (AB^2+BC^2)
=square root symbol [(15×15)+(4×4)]
= 15.5242cm (6sf)
Answer:
The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects.
Step-by-step explanation:
It is the last option. The perpendicular bisector theorem states that if a point lies on the bisector of a segment it is equidistant from the endpoints.
Meaning
If a perpendicular bisector is a line of the side of the triangle , it bisects the sides forming two right angles .
The first three choices are incorrect because
1) the figure shows a triangle bisected into two triangles and option 1 tells about 1 isosceles triangle.
2) The base angles of any triangle can be different or same .
3) the three perpendicular bisectors meet at a point called the circumeter. We have 1 perpendicual bisector which is dividing the triangle into two equal triangles.
Given, the plot is in the shape of triangle.
First side = x meter
Second side = ( 5x-3 )meters
Third side = ( 7x-6 ) meters
Perimeter of triangle is equal to the sum of all the three sides.
Perimeter = 
Combine like terms by adding all the x terms together and all the constant terms together.
Perimeter =
