Answer:

7f

Step-by-step explanation:

<em>To</em><em> </em><em>simplify</em><em> </em><em>you</em><em> </em><em>will </em><em>need</em><em> </em><em>to</em><em> </em><em>do</em><em> </em><em>it</em><em> </em><em>the</em><em> </em><em>same</em><em> </em><em>way</em><em> </em><em>as</em><em> </em><em>in</em><em> </em><em>adding</em><em> </em><em>natural</em><em> </em><em>numbers</em><em> </em><em>the</em><em> </em><em>variabl</em><em>e</em><em> </em><em>doesn't</em><em> </em><em>change </em><em>the</em><em> </em><em>number</em>

<em>So</em><em> </em><em>it</em><em>'s</em><em> </em><em>going</em><em> </em><em>to</em><em> </em><em>be</em><em>;</em>

<em>9</em><em>f</em><em>+</em><em>1</em><em>0</em><em>f</em><em>-</em><em>1</em><em>2</em><em>f</em>

<em>(</em><em>Nine</em><em> </em><em>plus</em><em> </em><em>Ten</em><em> </em><em>is</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>1</em><em>9</em><em>)</em><em> </em>

<em>•</em><em>T</em><em>h</em><em>e</em><em> </em><em>variable </em><em>remains</em><em> </em><em>the</em><em> </em><em>same</em>

<em>1</em><em>9</em><em>f</em><em>-</em><em>1</em><em>2</em><em>f</em>

<em>•</em><em>S</em><em>o</em><em> </em><em>you</em><em> </em><em>subtract</em><em> </em><em>1</em><em>2</em><em> </em><em>from</em><em> </em><em>1</em><em>9</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em>going</em><em> </em><em>to</em><em> </em><em>be</em><em>;</em><em> </em>

<em>7</em><em>f</em>

Find the value of x in kite EFGH<br>​
kolbaska11 [484]

Answer:

x = 105

Step-by-step explanation:

the sum of all interior angles of any four-sided figure has 360 degrees

∡F and ∡H are equal

add all four expressions and set them equal to 360

x + (x + 5) +( x + 5) + (140 - x) = 360

combine like terms

2x + 150 = 360

2x = 210

x = 105

What value of x will make ONM similar SRQ by the SAS similarity theorem?
Marta_Voda [28]

Answer:

The correct answer is 25

Step-by-step explanation:

See the attached figure.

SAS similarity theorem mean that when two triangles have corresponding angles are congruent and corresponding sides with identical ratios the triangles are similar.

So, if ΔONM similar ΔSRQ by the SAS similarity theorem

∴∠N = ∠R

And

\frac{NM}{RQ} =\frac{NO}{RS}

given that NM = 10 , NO = 8 , QR = x , RS = 20

∴\frac{10}{x} =\frac{8}{20}

∴x=\frac{10*20}{8} =25

So, the value of x will make ONM similar SRQ by the SAS similarity theorem = 25
