Hi,

From the picture you can see how 5x and 4x add up to 90°.

4x + 5x = 90°
9x = 90°
x = 10°

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.

PLEASE HELP ME!! 1.02: Triangle Similarity 1<br><br> What is the value of X?
hichkok12 [17]

Answer:

<h2>x = 28</h2>

Step-by-step explanation:

ΔARP and ΔCRD are similar. Therefore the sides are in proportion:

\dfrac{AR}{CR}=\dfrac{PR}{DR}

We have:

AR = 10 + x

CR = x

PR = 15 + 42 = 57

DR = 42

Substitute:

\dfrac{10+x}{x}=\dfrac{57}{42}           <em>cross multiply</em>

42(10+x)=57x             <em>use distributive property</em>

(42)(10)+(42)(x)=57x

420+42x=57x         <em>subtract 42x from both sides</em>

420=15x            <em>divide both sides by 15</em>

x=28
