Leona [35]3 years ago
3 0

Answer:

<h2>          A.   \bold{a=\dfrac92\ ,\quad b=\dfrac{15}2}</h2>

Step-by-step explanation:

The segment 6 is dividing the large triangle to similar triangles, so:

\dfrac a6=\dfrac b{10}=\dfrac68

Therefore:

\dfrac a6=\dfrac68\\\\8a=36\\\\a=\dfrac{36}8=\dfrac92            and            \dfrac b{10}=\dfrac68\\\\8b=60\\\\b=\dfrac{60}8=\dfrac{15}2

Shirley is drawing triangles that have the same area. The base of each triangle varies inversely with the height. What are the p
Romashka-Z-Leto [24]
1. First, you must find the constant of variation (k). The problem indicates that t<span>he base of each triangle varies inversely with the height. So, this can be represented as below:
</span>
 B=k/H

 B is the base of the triangle (B=10).
 H is the height of the triangle (H=6).
 k is the constant of variation.

 2. When you clear "k", you obtain:

 B=k/H
 k=BxH
 k=10x6
 k=60

 3. Now, you have:

 B=60/H

 4. You can give any value to "H" and you will obtain the base of the second triangle.

 5. If H=12, then:

 B=60/H
 B=60/12
 B=5

 6. Therefore, <span>the possible base and height of a second triangle is:
</span>
 B=5
 H=12
