Answer:
154 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon is 540.
Hence to get the 2 angles,
52+90+90+2n = 540
232 + 2n = 540
2n = 308
n = 154
Answer:
A= 45 degrees
Step-by-step explanation:
aight so basic info here: all triangles are equal to 180 degrees knowing this we gotta make equation
80+7x-4+8x-1=180
combine like terms
75+15x=180
15x= 105
x= 7
now plug it back in
7(7)-4
49-4
45
Answer:0.019 i think
Step-by-step explanation:
you would use the variability formula which is the squareroot p(1-p)/n
Answer:
y = 4x² - 4
Step-by-step explanation:
y = a(x - x₁ )(x - x₂)
Plug in the knowns
y = 4(x - 1)(x + 1)
expand
y = 4(x² - 1)
y = 4x² - 4
