Answer:
The missing side length is 6.
Step-by-step explanation:
Because the two triangles are similar,
the following equation of ratios is true:
m 4
----- = -----
15 10
Cross-multiplying, we get:
10m = 60, or m = 60/10 = 6
The missing side length is 6.
It would Bc j due to it being in middle of them
the answer is D my teacher just went over this hope this helps you
The answer for the question shown above is the las option, which is: <span>D. 2:3 and 4:9.
The explanation is shown below:
1. You have that</span><span> widths of the two similar rectangles are 10 cm and 15 cm. Therefore:
</span> ratio=10:15
ratio=2:3
2- So, the ratio of the perimeter is:
ratio of the perimeter= 2:3
3- The ratio of the areas is:
ratio of the areas=2²:3²
ratio of the areas=4:9
