Answer:
x = 6
Step-by-step explanation:
Similar triangles mean that it is the same shape (with same angles) but different side lengths. To find out "x", the scale factor is needed first. The scale factor is the amount that one side length is scaled (or multiplied) to equal the corresponding side length on the other similar shape.
To find the scale factor, pick a corresponding side that both triangles have a value, such as the hypotenuse, 15 and 9.
15 / 9 = 5/3 (scale factor)
The corresponding side for x is 10.
With the scale factor, divide 10 by it and x equals 6.
Mark as brainliest if I helped :)
1. EQUAL TO
2. LESS THAN
Hope this helps!! :)
Perimiter is where you add all the sides and a rectangle has four sides.
28/4=7
But the length is 4m longer then the width so, 7+4=11 but if we do 11+11+7+7= 36. But that is not the perimeter so 7-4=3
And if we do 11+11+3+3=28!
Therefore the length of the rectangle is 11m and the width is 3m
To find the area we just do 11•3=33
The only reason this is long is because i explained and put it into detail but its pretty simple and short once you get the hang of it :)
(3) has answer 7 and (4) is sqrt(32).
