Step-by-step explanation:
Start (A3)
x is equal to 141 because they are alternate interior angles.
A2. x is equal to 39 because they are corresponding angles.
B2. x would be supplementary to 41 because the angle that x supplements is corresponding to 41.
41 + x = 180 due to the linear pair postulate. Therefore, x = 139.
B1. x would be supplementary to 82 because they are consecutive exterior angles.
82 + x = 180 due to the linear pair postulate. Therefore, x = 98.
C1. x = 102 due to the vertical angles theorem.
C2. x would be supplementary to 130 because the angle that x supplements is equal to 130 (Alternate Exterior Angles).
130 + x = 180, x = 50.
D2. x = 74, corresponding angles.
D3. x = 83, corresponding angles.
D4. x = 95, corresponding
C4. x is supplementary to 18 because of the consecutive interior angles theorem.
x = 162

Answer:
See below
Step-by-step explanation:
4 more than 3: 3 + 4 = 7
5 out of 9: 5/9
the sum of 6 and 8: 6 + 8 = 14
10 less than 14: 14 - 10 = 4
the product of 3 and 4: 3 * 4 = 12
the ratio of 2 to 3: 2/3
10 decreased by 8: 10 - 8 = 2
the quotient of 23 and 25: 23/23
3 increased by 33: 3 + 33 = 36
50% of 32: 50% * 32 = 0.5 * 32 = 16
hello :
<span>help :
<span>the discriminat of each quadratic equation :
ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x =
(-b±√Δ)/2a</span>
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions</span>
