Answer:

G. \frac{3.2}{2} = \frac{a}{8}

Step-by-step explanation:

Given that figure I and figure II are similar, it follows that the ratio of their corresponding side lengths are equal and the same.

Thus:

\frac{3.2}{2} = \frac{a}{8} = \frac{8}{5} = \frac{6.4}{b}

Therefore, the proportion that must be true is:

✔️\frac{3.2}{2} = \frac{a}{8}

[7,8] is the difference between
Salsk061 [2.6K]

Answer:

The value of a is 3.

Step-by-step explanation:

Let be \vec a = \langle a, 5 \rangle and \vec b = \langle -4,-3 \rangle, the difference between the two vectors is:

\vec c = \vec b - \vec a

\vec c = \langle a, 5\rangle - \langle -4,-3 \rangle

\vec c  = \langle a+4,8 \rangle

If we know that \vec c = \langle 7,8 \rangle, the value of a is:

\langle 7, 8 \rangle = \langle a+4, 8\rangle

In which,

a + 4 = 7

a = 3

The value of a is 3.
