100 because opposite angles are equal. The angles in the triangle above add up to 80 so the last angle must equal 100. Since angle 1 is directly opposite to that angle, it also equals 100.

Teresas restraunt bill comes to $29.99 before tax. If the sales tax is 6.25% and she tips the waiter 20%. What is the total cost
alisha [4.7K]

Answer:

$37.86

Step-by-step explanation:

Multiply 29.99 by 0.0625 to get the sales tax

29.99x0.0625=1.87

Multiply 29.99 by 0.20 to get the tip

29.99x0.20=5.998

Round 5.998 to 6

Add 1.87 to 29.99

29.99+1.87=31.86

Add 6 to 31.86

31.86+6=37.86

The matrix to solve
Maurinko [17]
This question is impossible to solve.

this is why:

if 4x-4=0
then x=1

so if 8x + 4 = 8

then x is false.

I get these question quite a lot in my GCSEs.

you have to prove why they are fake.
