Answer:

Step-by-step explanation:

total cost of the meal = $120

tip = 20%

tip amount = ?

total cost of the meal with tip = ?

tip amount = tip% 0f total cost of the meal

=20/100 * $120

=$2400/100

=$24

total cost of the meal with tip = total cost of the meal without tip + tip amount

=$120 + $24

=$144

Answer:

See below

Step-by-step explanation:

Given :-

y || z

To Prove :-

m∠5 + m∠2 + m∠6 = 180°

Proof :-

Here we are required to prove that ,

$\rm\implies m\angle 5 + m\angle 6 + m\angle 2 = 180^o$

And here it's given that , y || z . Therefore ,

∠3 = ∠6 ( alternate interior angles )
∠1 = ∠5 ( alternate interior angles )

Now we know that the measure of a straight line is 180°. Therefore ,

$\rm\implies m\angle 1 + m\angle 2 + m\angle 3 = 180^o \\\\\implies\boxed{\rm m\angle 5 + m\angle 6 + m\angle 2 = 180^o}$

From 1 and 2 .

Hence Proved !
