Here, ∠1 + ∠2 = 180 [ Supplementary Angles ]

∠1 + ∠6 = 180 [ ∠2 = ∠6 ]
(corresponding angles)

123.5 + ∠1 + 180
∠1 = 56.5

In short, Your Answer would be Option A

Hope this helps!

A web page designer creates an animation in which a dot on a computer screen has a position of r⃗ =[ 4.2 cm +( 2.5 cm/s2 )t2]i^+

tankabanditka [31]

we are given

$r(t)=(4.2cm+(2.5cm/s^2)t^2)i+(5.5cm/s)tj$

Firstly, we will plug t=0 and t=2

Calculation of r(0):

$r(0)=(4.2cm+(2.5cm/s^2)*0^2)i+(5.5cm/s)*0j$

$r(0)=4.2i+0j$

Calculation of r(2):

$r(2)=(4.2cm+(2.5cm/s^2)*2^2)i+(5.5cm/s)*2j$

$r(2)=(4.2+5)i+(11)j$

$r(2)=(9.2)i+(11)j$

Average velocity:

now, we can use formula

$v=\frac{r(2)-r(0)}{2-0}$

now, we can plug values

$v=\frac{((9.2)i+(11)j)-(4.2i+0j)}{2-0}$

$v=\frac{5i+11j}{2-0}$

$v=(2.5cm/s) i+(5.5cm/s)j$ ..............Answer
