Mathematics geometry question. triangle abc

wariber [46]

Answer:

This will be s - r.

Step-by-step explanation:

Here,

SinB = r

CosB = s

SinB = AC/BC

Also,

CosC = AC/ BC

So, we can say SinB = CosC = r

Again,

CosB = AB/ BC

Also,

SinC = AB/ BC

So,

CosB= SinC = s

So,

SinC - CosC = s - r

Is 9-8x=y proportional

andrew-mc [135]

Answer:

No, proportional relations are of the form,

$y = mx$

Step-by-step explanation:

The given equation is

$9 - 8x = y$

This is an equation in the form:

$y = mx + c$

since we can rewrite to get:

$y = - 8x + 9$

This equation has a non-zero y-intercept and does not pass through the origin.

A proportional relation, will have a zero y-intercept and pass through the origin.

Therefore a proportional relation is of the form,

$y = mx$

If you could help me with this it would be greatly appreciated!

Ierofanga [76]

Here is your answer

B. $\sqrt{81}$

C. 9

REASON:

Let the side of square be a feet

Area of square = ${a}^{2}$

so,

${a}^{2}= 81$

$a= \sqrt{81}$

$a= 9 feet$
