Answer:
x = 27
Step-by-step explanation:
∠ ABD and ∠ BDE are alternate angles and are congruent, then
∠ BDE = 72°
∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is
2x + 72 + 2x = 180
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27
From information given Lisa bought three items.
10 + 20 + 23 = 53 dollars ( which is total pre- tax cost)
The sales tax rate is at 7.2% . Value of this tax in dollars will be:
7.2 % of 53 → (7.2 / 100) × 53 → 0.072 × 53 = 3.816
So the tax rate value is 3.816
Total cost of items will be 53 + 3.816 = 56. 816
Rounded off to the nearest cent 56.816 = 56.80
Therefore Lisa paid a total of $ 56.80
Answer:
Red grapes.
Step-by-step explanation:
If you find how much one bag of each grape cost which is:
$13.00 ÷ 5 = 2.60 (1 bag of red grapes)
$5.08 ÷ 2 = $2.54 (1 bag of green grapes)
See the price and you'll know it is red grapes.
This question doesn't make sence to me could you explain
Because it is an isosceles triangle, the two base angles have to be the same, so
36°+36°=72°
angles in all triangles add up to 180°, so
180°-72°=108°
unknown=108°
