Answer:
your answer will be 8
Step-by-step explanation:
thank you!!
If you mean two of the same numbers that add to make 75, it's 37.5 ....?
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
For the part b of the question please find the attached image.
Answer:
the perimeter is of 148 m
Step-by-step explanation:
the perimeter is the sum of all sides so an square has all sides equal so we have
and the area is
so we find x
and now the perimeter
