Find the X and Y for the given kite

Mathematics

1 answer:

Kamila [148]2 years ago

Answer:

x = 9
y = 5

Step-by-step explanation:

PQ = QR Property of a kite

x + 4 = 13 Subtract 4 from both sides

x = 13 -4 Combine the right.

x = 9

3y+5 = x + 11 Put 9 in for x

3y + 5 = 9 + 11 Combine the right side

3y + 5 = 20 Subtract 5 from both sides

3y = 20 - 5 Combine the right

3y = 15 Divide by 3

3y/3 = 15/3

y = 5

Answer:

Step-by-step explanation:

using sine formula

let ∠ADB=y

then ∠CDB=180-y

∠DAB =180-(35+y)

$\frac{AB}{sin~y} =\frac{12}{sin ~35}} \\AB=\frac{12 sin y}{sin 35} \\\frac{BC}{sin(180-y)} =\frac{4x-4}{sin 20 } \\\frac{BC}{sin y} =\frac{4x-4}{sin 20} \\BC=\frac{(4x-4)sin y}{sin 20} \\But~AB=BC (given)\\\frac{12 sin y}{sin 35} =\frac{(4x-4)sin y}{sin 20} \\\frac{4x-4}{sin 20} =\frac{12}{sin 35} \\4(x-1)=\frac{12 sin 20}{sin35} \\x-1=\frac{3 sin 20}{sin35} \approx 1.789\\x \approx 2.789$

The diameter of a circle is 8 ft. Find the circumferenceto the nearest tenth.

AURORKA [14]

Answer:

25.1 ft

Step-by-step explanation:

To solve for circumference is pretty simple. Just use the equation 2pi r (r=radius, radius is diameter divided by 2).

So essentially, apply to your calculator:

2(3.14)4=25.12

pretty simple! hope this helps!
