If the measure of a triangle are in the ratio 2:5:5. What is the measure of the angle

1 answer:

5 0

Your answer is 75°, 75°, and 30°
Because you know that angles in a triangle equal 180°, you can find what 1 in terms of the ratio is by adding 2, 5, and 5, and then dividing 180 by that value. 2 + 5 + 5 = 12, so 180 ÷ 12 = 15.
Now that you know that 1 in terms of the ratio is 15, you can multiply 15 by the ratio values, so
15 × 2 = 30°
15 × 5 = 75°
15 × 5 = 75°

I hope this helps!

What is the equation of the graph????

tia_tia [17]

The graph shown above is a "parabola" and the parent function is x². So, we can start off at x². The graph of x² intersects the x and y-axis at (0, 0). In this case, it's simply being shifted up by 1 and intersects the x and y-axis at (0, 1). Therefore, the equation is:
$y = x^2 + 1$

To check, let's plug in 0 for x, and see what we get (we should get 1):
$y = x^2 + 1$
$y = 0^2+1 = 0+1=1$

We are right, so your final answer is x² + 1.
