Asapp! will mark brainlist i dont have enough time lotta points

<X = 48°

<Y  = 96°

<Z  = 36°

Step-by-step explanation:

<X +<Y+<Z = 180

3.2n + 6.4n + 2.4n = 180

12n = 180

n = 15

<X = 3.2(15) = 48

<Y = 6.4(15) = 96

<Z = 2.4(15) = 36

<X =48

<Y  =96

<Z = 36

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

3.2n + 6.4n +2.4n = 180

Combine like terms

12n = 180

Divide each side by 12

12n/12 =180/12

n =15

<X = 3.2 n = 3.2 *15 =48

<Y = 6.4 n = 3.2 * 15 =96

<Z = 2.4 n = 2.4 * 15 =36

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

see attached

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
