Answer:

x=30

Step-by-step explanation:

all interior angles in a triangle must equal 180 degrees

2x+30+90=180

2x+120=180

2x=60

x=30

you can check by substituting 30:

2(30)+30+90

60+30+90=180

another way to do this:

3x is an exterior angle

however it is a supplementary one as well

that means tht

3x+90=180

3x=90

x=30

you get the same answer either way

HOPE THIS HELPS!

Answer:

30

Step-by-step explanation:

Exterior angle equals sum of opposite interior angles

3x = 2x + 30

3x - 2x = 30

x = 30

The sale tax rate is 7.5%. What is the tax on a $14.80 purchase.
SSSSS [86.1K]
Okay! Assuming this only wants the tax that will be added to the total, multiply the decimal percent by the cost of the item.

7.5% = .075

14.80 * .075 = 1.11

1.11 of tax will be added onto the total cost.

The total cost would be 15.91, which you can get from adding 14.80 to 1.11 or by doing 14.80 * 1.075. Regardless, the answer to this question is 1.11.
