It would be a acute because you would do 51+39=90 which u would do 180-90 which would equal 90 and a aucte is a 90 degree angle

Those two angles are complementary - which means they both give us 90 degrees. We know that all three angles in any triangle must be exactly 180 degrees, so the third angle will be 180 - 90 = 90 degrees. It means that our triangle is a straight triangle. The figure will look more less like in the attachment. <span> </span>

Is 8x-2y=2 a direct or inverse variation
sp2606 [1]

Answer:

Neither, why... for it to be direct or inverse variation, the model has to fit either y=k/x or y=kx, it may not have a y-intercept at all if it is inverse variation and it must have a y-intercept of 0 for it to be direct variation.

Step-by-step explanation:

The statement y=2 is quite specific. Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases.  yx is a constant number -8. The constant of variation, k , is 23 . Inverse Variation

An inverse variation can be represented by the equation xy=k or y=kx .

That is, y varies inversely as x if there is some nonzero constant k such that, xy=k or y=kx where x≠0,y≠0 .

Suppose y varies inversely as x such that xy=3 or y=3x . That graph of this equation shown.

The output with the y being -4
aivan3 [116]

For this case we have a function of the form y = f (x), where f (x) = - 4x. We must find the values of "and" according to the following function:y = -4x

So:

f (-6) = - 4 (-6) = 24\\f (-2) = - 4 (-2) = 8\\f (3) = - 4 (3) = - 12

Thus, the values are:

24,8, -12

Answer:

24,8, -12

A circle has a diameter of 8cm, what is the perimeter and the area of the circle
Shkiper50 [21]

Answer:

❥

Diameter of a circle is 8 cm. Then find out the area and perimeter of the circle.

❥

Area of circle is 50.29(≈)cm² and perimeter of circle is 25.14(≈)cm.

❥

•Given :-

Diameter of the circle = 8 cm.

•To find :-

Area and perimeter of the circle.

• Solution :-

Let the radius of the circle be r cm.

Diameter = 8 cm.

We know,

★

So, Radius (r) = 8/2= 4 cm.

We know,

★

Area of circle= πr²

→Area of circle=

→Area of circle=

→Area of circle= 50.29(≈)cm²

____________________________

We know,

★

Perimeter of circle= 2πr

→ Perimeter of circle=

→Perimeter of circle=25.14(≈)cm
