Answer:

A. 90°+m∠4

Step-by-step explanation:

Also

∠ A + ∠ C = 180 o = ∠ B + ∠ D

⇒ 2 x+ ( 3 x − 5 ) = 180 0 = ( x + 5 ) + ∠ C

5 x − 5 = 180

Add 5 to both sides

5 x = 185

Divide both sides by 5

x = 185 5 = 37

But it was A. 90°+m∠4

podryga [215]

Answer:

When $a=\frac{1}{4}$ and $b=6$ :

$-8ab=-12$

Step-by-step explanation:

-8ab can be seen as -8×a×b. Insert the given values:

$-8*\frac{1}{4} *6$

Simplify multiplication from left to right:

$-8*\frac{1}{4} \\\\\frac{-8}{1} *\frac{1}{4} =\frac{-8}{4} =-2$

Insert and solve:

$-2*6=-12$

Evaluate the polynomial function p (x) = 2x4 - 3x2 + x - 1 to find p (-1).

Alisiya [41]

$p(x)=2x^4-3x^2+x-1\\\\
Substitude\ p=-1\ into\ equation\\\\
p(-1)=2x^4-3x^2+x-1=2*(-1)^4-3(-1)^2-1-1=\\2*1-3*1-2=2-3-2=-3\\Answer\ p(-1)=-3$

When flying from Florida to the Philippines island why does the shortest route pass through Alaska?

seraphim [82]

Because the earth is round, the distance seen on a flat map is a lot further than the distance on a globe, because of distortion. So following the circle that goes through these 3 points ( Florida, Alaska and the Philippines) it is a shorter distance to fly over Alaska.
