∠DBC is bisected by ray BD: FALSE. BD IS ONE OF THE SIDES OF THE ANGLE DBC AND NOT A BISECTOR OR IT.
∠ABC is bisected by ray BD: TRUE. THE ANGLE ABC IS 180° AND THE RAY BB SPLITS IT IN TWO ANGLES 90° EACH.
BC = (1/2) AC: TRUE. GIVEN THAT B IS THE MIDPOINT OF AC, AB = BC AND AC = AB + BC = AB + AB = 2 * AB => AB = AC / 2
AB = (1/2) AC. TRUE. REMEMBER THAT AB = BC
DB congruent to BC: FALSE. YOU DO NOT KNOW THE LENGTH OF DB.
2m∠DBC = m∠ABC: TRUE. m∠DBC= 90° and m∠ABC = 180°
Answer:
T
Step-by-step explanation:
Answer:30 feet.
Step-by-step explanation: 2 doubled is four and in the bigger triangle it says 5. Therefore 12 doubled and a bit more is 30
Answer:
Option A is correct: A. The first kind of error would be saying that your friend can tell the difference between the two kinds of peanut butter, when she really can't.
Step-by-step explanation:
The null hypothesis: the lady is just guessing and should get about half right.
So the first kind of error (when you reject the null hypothesis when it is actually true): the lady is not just guessing and can tell the difference between the two kinds of peanut butter, whereas in reality, she can't tell the difference and is just guessing randomly.
Answer:
x=8
Step-by-step explanation:
- Pythagorean Theorem Formula: a^2+b^2=c^2
- Let a be x, let b be 6, and let c be 10.
- Plug x, 6, and 10 into the equation - x^2+6^2=10^2
- Simplify 6^2 and 10^2 - x^2+36=100
- Subtract 36 from both sides - x^2=64
- Take the square root of x^2 and 64 to get x by itself - x=8
