The point a has an x-ordinate of 3. Go straight to the left until your are under point C. You are now at an x-ordinate of -5. The horizontal distance from A to C is then 5- -3 = 8. Likewise, the vertical distance from A to C (the y-ordinate distance) is 5 - -1, or 6. Now we have a right triangle with legs 6 and 8. The Pythagorean Theorem then tell us the hypotenuse (straight line distance from A to C) is the square root of 6^2 + 8^2, or the square root of 100, which is 10..
$271.11 or $271.12 if you round up. Not sure how this one is complicated. Correct me if I’m wrong... 2.891.25 divided by 85. You then take that number and multiple it by 8. Seems very straight up.
Answer: A
<u>Step-by-step explanation:</u>
CD bisects ∠BCD and ∠ACD, so
∠BCD = ∠ACD
5x - 20 = 3x - 2
<u>-3x +20</u> <u>-3x + 20</u>
2x = 18
<u>÷2 </u> <u> ÷2 </u>
x = 9
∠BCD = 5x - 20 = 5(9) - 20 = 45 - 20 = 25
∠BCD + ∠CDB + ∠DBC = 180°
25 + 90 + ∠DBC = 180°
115 + ∠DBC = 180°
<u> -115 </u> <u>-115 </u>
∠DBC = 65°
