Help me plsss i am soo bad at this

lara [203]

Step-by-step explanation:

GIVEN: O is the mid point of AC & BD.

Therefore, AO = CO & BO = DO

$\therefore \: AO \: \cong \: CO.. (given) \\ \\ \: \: \: \: \angle \: AOB \: \cong \:\angle \:COD\\..(vertically\:opposite\:angles) \: \\ \\ \& \: \: \: BO \: \cong \: DO.. (given) \\ \\ \therefore \triangle \: AOB \: \cong \: \triangle \:COD \\ ..(by \: SAS \: test \: of \: congruence ) \\ \\ \therefore AB = CD.. \\ (Corresponding \: sides \: of \: congruent \: triangles)$

T=v /6 + 5<br> a) Work out the value of T when v = 42

Leno4ka [110]

The value of T in the equation if v = 42 is 12

<h3>How to solve algebra</h3>

Given:

T= v /6 + 5

If v = 42, find T

substitute 42 for v in the equation

T= v /6 + 5

T = 42/6 + 5

solve the fraction first

T = 7 + 5

T = 12

Therefore, the value of T in the equation if v = 42 is 12
