Given:
ABCD is a cyclic quadrilateral.
m∠C = 43°
To find:
The measure of ∠A.
Solution:
<em>In cylic quadrilateral, opposite angles are supplementary.</em>
⇒ m∠A + m∠C = 180°
⇒ m∠A + 43° = 180°
Subtract 43° from both sides.
⇒ m∠A + 43° - 43° = 180° - 43°
⇒ m∠A = 137°
The measure of ∠A is 137°.
Answer:
33.60
Step-by-step explanation:
First determine the discount
40 * 20%
40 *.2 =8
The discount is 8
40-8 = 32
The shirt was 32 dollars before tax
Now find the tax
32 * 5%
32*.05 =1.60
Add the tax to the sale price
32+1.60
33.60
The unit rate in dollars per ounce would be $403.90.
Hope this helps! :D
