Answer:

80°

Step-by-step explanation:

<A+<B+<C=180

30+<B+70=180

100+<B=180

<B=180-100

= 80

consider triangle ABC and triangle EDC

AC=CE (given

BC=CD (given

<ACB=<ECD (vertically opposite angles are equal)

therefore triangle ABC is congruent to triangle EDC

<B=<D (CPCT)

A3-b3=(a-b)(a2+an+b2) 64x6-27
olga nikolaevna [1]
<span>a³-b³=(a-b)(a²+ab+b²)

64x⁶ - 27

64 = 4³, 
x⁶ = (x²)³
27 = 3³

</span>64x⁶ - 27 = 4³(x²)³ -3³ = (4x²)³ -3³.  Now, we can use a formula where a=4x², b=3

(4x²)³ -3³ = (4x² -3)((4x²)² +4x²*3 + 3²) =  (4x² -3)(16x⁴ +12x² + 9) 
<span>
Answer: </span>64x⁶ - 27=  (4x² -3)(16x⁴ +12x² + 9) <span>
