Answer:

x = 13.86

y = 6.93

Step-by-step explanation:

tan 30° = y/12

0.5774 = y/12

y = 12(0.5774) = 6.93

cos 30° = 12/x

0.8660 = 12/x

In ΔIJK, i = 850 inches, j = 250 inches and ∠K=80°. Find the length of k, to the nearest inch.

Answers

Answer:

886 inches

Step-by-step explanation:

Because we know the length for sides I and J, we can use the pythagorean theorem to get K. 850^2 + 250^2=KY^2. 850^2 = 722,500, and 250^2 = 62,500. 722,500 + 62,500 = 785,000. 785,000 to the square root rounded to the nearest inch is 886 inches.

The sum of the three interior angles of a triangle is always 180.

Knowing this, we can set up an equation for the given angles:

[tex]8x + 10x + 12x = 180[/tex]

[tex]30x = 180[/tex]

[tex]x = 6[/tex]

Knowing this, we can now plug it into the angles:

Quadrilateral ABCD ​ is a rectangle. BE=2x+1 and AC=6x−12 . What is BE ?

Answers

Answer:

BE=15

Step-by-step explanation:

Since E is the center, BE=2x+1

And AC is 6x-12 with E being a midpoint.

Since AC is 2 segments and BE is only 1 then you multiply 2x+1 by 2 so that

you can find x. You multiply 2x+12 by 2 because E is the midpoint so that means ED is the same value as BE

6x-12=4x+2

BD=AC

6x-4x-12=2

2x=2+12

2x=14

x=7

BE= 2x+1

2(7)=14+1=15
