Answer:

see explanation

Step-by-step explanation:

Since lines a and b are parallel, then

∠NMP and ∠MPQ are same side interior angles and are supplementary, thus

a + a - 20 = 180

2a - 20 = 180 ( add 20 to both sides )

2a = 200 ( divide both sides by 2 )

a = 100, hence

∠NMP = a = 100° and

∠MPQ = a - 20 = 100 - 20 = 80°

<h2>Question :</h2>

<h3>Solve the proportion : </h3>

$\sf \dfrac{24}{2} = \dfrac{t}{7}$

<h2>Answer :</h2>

$\sf \dashrightarrow \:\dfrac{24}{2} = \dfrac{t}{7}$

$\sf \dashrightarrow \: \cancel{\dfrac{24}{2}} = \dfrac{t}{7}$

$\sf \dashrightarrow \:12 = \dfrac{t}{7}$

$\sf \dashrightarrow \:12 \times 7 = t$

$\sf \dashrightarrow \:84 = t$

$\sf \dashrightarrow \:t = 84$

Hence, The solution is $\large \underline{\boxed{\sf t = 84}}$

Step-by-step explanation:

The rectangle area is equal to LENGTH * WIDTH

then

t^2-16t+48 = L*W

L = [t^2-16t+48] / W

and

t^2-16t+48 = L*W

W = [t^2-16t+48] / L

Answer:

$\boxed{u = 6.0}$

Step-by-step explanation:

Using the cosine rule

$c^2= a^2+b^2-2abCosC$

Here c = u , a = 11 , b = 12 and C = 30

$u^2 = 11^2+12^2-2(11)(12)\ Cos 30\\u^2 = 121+144-2(132)(0.866)\\u^2 = 265-228.6\\u^2 = 36.37$

Taking sqrt on both sides

u = 6.0 (To nearest tenth)
