Answer:

angle ABC is 48⁰

Step-by-step explanation:

angle BCD will be 111⁰ it will be equal to DAB.

111+111+90=312⁰

kite is a quadrilateral so its angles add up to 360⁰

360-312=48⁰

Step-by-step explanation:

ΔA = ΔC = 111° (kite property-opposite Δ equal)

ΔD = 90° ------ ( given )

ΔA + ΔB + ΔC + ΔD = 360°

111° + ΔB + 111° + 90° = 360°

312° + ΔB = 360°

ΔB = 360° - 312°

ΔB = 48°

Im seriously in need of help anybody im not joking around please!!!!!

Answer:

A.) = 6

If RE = 12, then RD = 6

B.) = 10

If BR = 10, then BE = 10

C.) = 16

If BD = 8, then BK = 16

D.) = 30*

<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*

E.) = 60*

If <m2 = 60*, then <m3 = 60*

F.) = 90*

It`s a 90* angle because BK and RE and perpendicular

G.) = 60*

If <m1 = 30*, then multiply by two because it is symmetrical

I would show all my work but you seem to be in a rush. Hope this helps!

A quadrilateral has two angles that measure 222° and 81°. The other two angles are in a ratio of 6:13. What are the measures of

hram777 [196]

$\sf\huge\underline{\star Solution:-}$

$\rightarrow$ Ratio of two angles are 6:13.

So, let the one angle be $\sf{6x}$ and another be $\sf{13x.}$

As we know that,

Sum of all interior angles of a quadrilateral = $\sf\pink{360°.}$

So let's sum up the given angles,

$\rightarrow$ $\sf{222°+81°+6x+13x \:=\: 360°}$

$\rightarrow$ $\sf{303+19x \:=\: 360°}$

$\rightarrow$ $\sf{19x \:=\: 360-303}$

$\rightarrow$ $\sf{19x \:=\: 57}$

$\rightarrow$ $\sf{x \:=\: \frac{19}{57}}$

$\rightarrow$ $\sf{x \:=\: 3}$

Hence, $\sf{x \:=\: 3}$

So, First angle $\sf{= \:6x\: = \:6×3 \:=}$ $\sf\purple{18°.}$

Second angle $\sf{= \:13x\: = \:13×3 \:=}$ $\sf\purple{39°.}$

$- \frac{2}{3} - ( - \frac{4}{6} ) = \\$

$- \frac{2}{3} + \frac{4}{6} = \\$

$- \frac{2}{3} + \frac{2 \times 2}{2 \times 3} = \\$

$- \frac{2}{3} + \frac{2}{3} = 0\\$

Use the Product Property for Exponents to explain why x · x = x2.

Lubov Fominskaja [6]

Whenever there is no exponent on a variable,

you can give it an exponent of 1.

So we can rewrite the x's in this problem as x¹.

When we multiply two terms together

with like bases, we add their exponents.

So now just add their exponents to get x².
