Answer:
41 feet
Step-by-step explanation:
We apply the theorem below:
If two similar triangles have a scale factor of a : b, then the ratio of their perimeters is a : b.
Let x be the perimeter of the smaller triangle
If the ratio of their heights is 6:5 and the perimeter of the larger triangle is 49.2 feet,
6:5=49.2:x
6/5=49.2/x
Cross multiplying
6x=49.2 X 5
6x=246
x=246/6=41
The perimeter of the smaller triangle is 41 feet
642 ion wanna show the work good luck doe
Answer:
first triangle (to left) b=8, second one c=17
Step-by-step explanation:
for the first triangle (one to the left) the hypotenuse is 9, so let's use the pythagorean formula.
A^2 + B^2 = C^2
^ ^ ^
^ ^ Hypotenuse
^ second side
first side
Substitute:
5^2 + b^2 = 9^2
SImplify:
25+b^2 = 81
Reduce:
b^2 = 64
Simplify:
b=8
In the second triangle, we are given 2 sides.
Let's do the same thing we did in the first one.
Givens:
A = 8
B = 15
Find:
C
Substitute:
8^2 + 15^2 = c^2
Simplify
64 + 225 = c^2
Reduce:
289 = c^2
Let's now square root both sides
square root of 289 is 17
so we are left with this:
c=17
Phew, you did it!
Hope this helped :))
70mm times 99mm which gets you to 6390mm
or
210mm times 297mm = 62370mm squared
