Answer:
Your teacher is correct.
Step-by-step explanation:
So first we would have to find what A is equivalent to which is 48. This is because 180 - 132 = 48. Since we know that 132 is a supplementary angle, there has to be another supplementary angle that results in the sum of 180.
With this information in mind, we can create the expression:
2x + 4x + 48 = 180 (A triangle is equal to 180 degrees)
Now simply the equation:
6x + 48 = 180
6x = 132
6x/6 = 132/6
x = 22
Angle C = 44
Angle B = 88
2x+1=27032
2x=27031
x=13515.5
2x+3
=2(13515.5)+3
=27034
Answer:
x = cuberoot( -9/8)= -1.04004 or x = cuberoot(1/2)=0.7937
Step-by-step explanation:
let y = x^3 + 1
we have:
16*(y) ^2 - 22 (y) - 3 = 0
16 = 2* 8
-3 = -3* 1
8*-3 + 2 = -24 + 2 = -22
Factor as (8y + 1)(2y - 3) = 16 (y)^2 - 22(y) - 3 = 0
so (8y + 1) = 0 or 2y - 3 = 0
y = -1/8 OR y = 3/2
with y = x^3 + 1
solve for x
-1/8 = x^3 + 1
x^3 = - 9/8
x = cuberoot( -9/8)
about x = -1.04004
or 3/2 = x^3 + 1
1/2 = x^3
x = cuberoot( 1/2 ) = 0.7937
