The angles of a triangle add to 180, add the angles and solve for x
Answer:
11.2
Step-by-step explanation:
If the rectangulars are similar then we can use similarity ratio to calculate value of x
CD is similar to RS and AB is similar to QP
4/6.4 = 7/x cross multiply expressions
4x = 44.8 divide both sides by 4
x = 11.2
Answer:
32768
Step-by-step explanation:
<h2><u>SIMPLIFY</u></h2>

<h3>now make use of the exponent rule :</h3>



=
<h3>apply the exponent rule:</h3>


= <u>32768</u>
If we place 0 and 1 for the x then:

this is the line:
