Answer:

x= 4

y = 6

Step-by-step explanation:

Given:

RSU is equilateral triangle

RT bisects US

To Find:

x and y

Solution:

Step 1: Finding the value of x

In an equilateral triangle,

All the sides are equal

Since RT bisects US

US =  3x+3x

Also RU  =  4x+8

Then ,

we know that

RU = US

4x+8 = 3x+3x

4x+8 = 6x

4x+ 8 -6x = 0

-2x+8 = 0

-2x = -8

x = \frac{-8}{-2}

x = 4

Step 2: Finding the value of y

In an equilateral triangle,

All the angles are equal  to 60 degrees

Then \angle URS = 30^{\circ}

But RT bisects US

Then

\angle URS = \angle URT +\angle TRS = 60^{\circ}

where

\angle URT and \angle RTS are equal

So

\angle RTS   = 30^{\circ}

In the figure

30^{\circ}  = 5y^{\circ}

y^{\circ}= \frac{30^{\circ}}{5}

y^{\circ} = 6

Kite DCFE is inscribed in circle A shown below.
kogti [31]

Answer:

∠DEF =56°

Step-by-step explanation:

We are given that arc DEF = 248°

So, arc DCF = 360°-248°

arc DCF = 112°

Now we are required to find the ∠DEF.

So, we will use Inscribed angle theorem.  

Inscribed angle theorem: The measure of an inscribed angle is equal to one-half the measure of its intercepted arc.  

Intercepted arc = arc DCF = 112°

Inscribed angle = ∠DEF

⇒∠DEF = \frac{1}{2}arcDCF

⇒∠DEF = \frac{1}{2}\times 112^{\circ}

⇒∠DEF =56°

Hence the measure of ∠DEF =56°

Which is the correct answer​
Sav [38]

Answer:

Option 3

Step-by-step explanation:

Using the order of operations, you will find out that 7 x 10^3 = 7,000, and 3 x 10^2 = 300. Dividing 7,000 by 300 will get you 23.333~, so 300 does go into 7,000 a little more than 20 times.

9-t=t+3
Subtract t on both sides
-2t=-6
Divide by -2 to leave the variable by itself
