Complementary angles are either of 2 angles that when added together equal 90. We can solve this by setting up a simple equation.

 65+x=90
-65     -65
x=25

Using the equation above, we can see that ∠A=25.<u />

Can you guys please answer this is really important

Answer:

B) BC'= 8, m A'= 28°

Step-by-step explanation:

When dilating a figure, it increases its size or decreases. In this case, as it is dilating by a factor of 1/2, you can assume it decreases.

To find the value of the new figure, A'B'C', you have to multiply the factor times the lengths of the triangle, or, the only one they are asking for in this case, the length BC':

  • BC' = BC×1/2
  • BC' = 16×1/2
  • BC' = 8

The angles, otherwise, do not change. When figures are dilated, they are similar. The properties of similar figures are that they have congruent angles, therefore, the same angles. They do not have any effect caused by the factor, so m A' stays at 28°.

20 POINTS !!!!<br> The roots of the equation x^2+bx+c=0 are −4 and 2. Find b.
Irina18 [472]

first, love the killua profile picture ! i love hunterxhunter i am currently on season 5, episode 44 or 45 aka 119 or 120 but anyways,

answer:

b = 2

step-by-step explanation:

because its roots are -4 and 2,

and a = 1 [The coefficient of x^2] we know that x^2 + bx + c = (x - (-4)) (x-2)=(x+4)(x-2) = 0.

using the distributive property we get,

x^2 + 2x - 8 = 0.

by equating coefficients (common strategy for partial fractions and undetermined coefficient method of solving ODE), we get b = 2 and c = -8 ( solved c just for fun guess :) ) .

hope this helps :)
