Same signs add and keep, different signs subtract and keep the sign of the higher number. If you subtract intergers you keep,change, change the signs .

CAN SOMEONE PLEASE HELP ME WITH MY GEOMETRY HOMEWORK PLEASE?

Kay [80]

Answer:

Option A

Step-by-step explanation:

The complete question is shown in the attachment.

The sum of angles in a triangle is 180 degrees.

This implies that:

$m\angle A+85+53=180$

m<A+138=180

m<A=180-138=42

Now we use the sine rule to find AC=b

$\frac{b}{\sin 85}=\frac{85}{\sin 42}$

This implies that:

$b=\frac{85}{\sin 42}*\sin 85$

$b=126.5$

Why are points and lines hard to define?

Sliva [168]

Because when we draw a point ,we draw a very very small line....one can see how this might lead to a problem.consider a line that is 1 inch long,what we want to looked at 1/1000 through that line it would still be a line.but,if we drew it ,it would look like a point....

If the area of the blue square is 144 units2 and the area of the pink square is 1225 units2, then the length of the hypotenuse i

navik [9.2K]

Answer: 37 units

Step-by-step explanation:

$Blue=144units^2$ This also works as the height of the triangle.

$Pink=1225units^2$ This also works as the base of the triangle.

Let's call pink ''a'', and blue ''b''. The side we're looking for ''c'' is the hypothenuse.

To find the values of a and b, use the area formula of a square and solve for a side. In this case, since we're going to need the squared values, this step can be omitted.

$Formula: A=s^2$
