Answer:

50°

Step-by-step explanation:

ABCD is a kite.

Therefore, AB = BC

$\therefore m\angle BCA= m\angle BAC = 40\degree \\\because BD \perp AC.. (Diagonals \: of\: kite) \\\therefore y + 90\degree + m\angle BCA = 180\degree \\\therefore y + 90\degree + 40\degree = 180\degree \\\therefore y = 180\degree - 130\degree \\\huge\red {\boxed {y = 50\degree}}$

SOMEONE PLEASE HELP ME!!! ILL GIVE YOU BRAINLIST <3 PLEASE THANK YOU

<u>Step by Step Explanation:</u>

16. x - 4 = 4

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 4 (+4)

x = 4 + 4

x = 8

17. a/4 = 4

Isolate the variable (a). Note the equal sign, what you do to one side, you do to the other. Multiply 4 to both sides:

(a/4)(4) = (4)(4)

a = (4)(4)

a = 16

18. y * 20 = 30

Isolate the variable (y). Note the equal sign, what you do to one side, you do to the other. Divide 20 from both sides.

(y *20)/20 = (30)/20

y = 30/20

y = 3/2 or 1.5

19. x/5 = 20

Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Multiply 5 to both sides

(x/5)(5) = (20)(5)

x = (20)(5)

x = 100

Help!<br> Ratios and Porportions

SOVA2 [1]

We learned that ratios are value comparisons, and proportions are equal ratios. Ratios can be written with colons or as fractions. So, to compare the number of girls to boys in a litter of puppies, we can write 2:4 or 2/4 to say that there are two girls to four boys.

A field in the shape of a trapezoid has an area of 13.687.5 square yards the length of one base is 150 yards and the length of t

AURORKA [14]

This question is not correctly written

Complete Question

A field in the shape of a trapezoid has an area of 13,687.5 square yards the length of one base is 150 yards and the length of the other base is 215 yards what is the height of the trapezoid

Answer:

The height of the trapezoid is 75 yards

Step-by-step explanation:

Area of a Trapezoid = 1/2(b1 + b2) × h

Where b1 = Length of the first base

b2 = Length of the second base

h = height of the trapezoid

From the question

Area of the trapezoid = 13,687.5 yd²

b1 = Length of the first base = 150 yards

b2 = Length of the second base = 215 yards

h = height of the trapezoid

Hence, we have

13,687.5 = 1/2(150 + 215)h

13,687.5 = 365h/2

13,687.5 × 2 = 365h

h = 13687.5 × 2/365

h = 75 yards

Therefore, the height of the trapezoid is 75 yards.
