Sorry I'm late! xx
Okay, so two of the sides in an isosceles triangle are of the same length. The lengths are either in the ratio 5:5:6 or 5:6:6
The perimeter is 32 cm
If we take the first ratio, 5:5:6, then we have 16 "parts". Let the length of each "part" be referred to as "x"
So, 16x = 32, and so x = 2
So, the ratio of the sides are 10 cm, 10 cm, 12 cm.
To find the height, "h", we need to use Pythagoras' Theorem, with 10 being the hypotenuse and 6 being the horizontal side (think of a line cutting straight down the middle of the isosceles triangle)
h^2 + 36 = 100
h = 8 cm
Area of a triangle is 0.5 x base x height. So, 0.5 x 12 x 8 = 48 cm^2
Hope I helped!! xx
Lcm stands for Least common multiple
The lcm of these numbers is 48
6 - 6, 12, 18, 24, 30, 36, 42, [ 48]
16 - 16, 32, [48 ]
Therefore 48 is the lcm because it is the lowest number 6 and 16 have in common
Answer:
n = 3; enlargement
Step-by-step explanation:
The dashed-line figure is larger. That is the meaning of "enlargement."
Points on the dashed-line figure are 3 times the distance from point H as the corresponding point on the sold-line figure, so the scale factor is 3.
3x-21=6x-60
3x+39=6x
39=3x
x=13
