Triangle- interior angles .<br> Please help !
valentinak56 [21]

Answer: x = 30

∠H = 75

∠I = 75

Step-by-step explanation:

Write out this equation for solving interior angles

The sum of all 3 angles will equal 180

(2x+15) + (3x-15) + 30 =180

2x + 3x +30 + 15 -15 = 180

2x + 3x + 30 = 180 ( subtract 15 from 15 )

2x + 3x + 30= 180

              -30   -30 ( from both sides)

2x + 3x = 150

5x = 150

Divide

x=30

Find the zeros of the function p(x) = -9x^2 + 1
morpeh [17]

Answer:

Zeros: 1/3 and -1/3

Step-by-step explanation:

You can solve this for the zeros by using the factoring method:

p(x) = (-3x-1)(3x-1)

Then, you take each factored equation and set it equal to zero:

-3x-1=0

3x-1=0

Then, solve for zero:

-3x=1    x=-1/3

3x=1     x=1/3

Your zeros are 1/3 and -1/3.
