180 - 35 = 145

second one:

ABC & DEC triangles are identical so:

[tex] \frac{30}{10} = \frac{x}{8} \\ x = 24[/tex]

third one:

[tex] \frac{6}{8} = \frac{x}{16} \\ x = 12[/tex]

Answer:

first question

B) 145

second question

AB = 24

Step-by-step explanation:

first question

<R = <STQ = 35 (corresponding angles)

<STR = 180 - 35  = 145

second question

Lets AB = x

10/8 =  30/x

10x = 240

   x=  24

So AB = 24
