8 0

Two complementary angles: α,β

Definition of complementary angles:
α+β=90
β=4α
4α+α=90
5α=90 /:5
α=18

Measure of smallest angle is 18 degrees.

45.6%, I think

If the angle was 45 degrees, then 50% of the circumference of the ice cream would be inside the cone.
But the real angle is 41. 41 = (41/45) * 45

So if we multiply 45 by 41/45, we get 41. In the same way, if multiply the "50%" by 41/45, we get the percentage of ice cream circumference that is in the cone.

50% * 41/45 = 45.6%

What is the value of (3x^2+1-1-x)(2) ?

Dafna1 [17]

Answer:

6x^2 -2x

Step-by-step explanation:

As written, the constant terms in the first factor cancel each other. The distributive property is used to perform the multiplication:

(3x^2 +1 -1 -x)(2) = (3x^2 -x)(2) = (3x^2)(2) -x(2)

= 6x^2 -2x
