Insta: 25k_kemWhat is one method to find the measure of angle B?
A. use the Pythagorean theorem to find BC, then solve the equation tan(B)=8/BC
B. because of the 30-60-90 triangle theorem, you know the measure of angle B is 60
C. solve the equation cos(B)=8/89(square rooted)
The answer is A
Answer:
A
Step-by-step explanation:

One method to find angle B is A. use the Pythagorean theorem to find BC, then solve the equation tan(B)=8/BC.
What is Pythagoras Theorem?Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.
Given is a right angled triangle ABC with the hypotenuse being AB and the legs AC is the base and BC is the height.
Given AC = 8 and AB = √89.
We need to find the measure for angle B.
Either we can find angle B using Sin B = Opposite side / hypotenuse
Sin B = 8 / √89
But this is not in the option.
So first find the length of BC using the Pythagoras Theorem.
(BC)² = (AB)² - (AC)²
= (√89)² - (8)²
= 25
BC = √25 = 5
We get the opposite side and adjacent side with respect to angle B.
Tan B = AC / BC = 8 / 5 = 1.6
B = 57.99° ≈ 58°
Hence the approximate measure of angle B is 58°.

Answer:
Reflection about y axis
Step-by-step explanation:
A reflection about the y axis will change the sign of the x coordinates
Answer:
Horizontal translation or a reflection around a vertical axis
Step-by-step explanation:
If the change in the x-coordinate has been the addition or subtraction of a constant number (same number for all vertices of the quadrilateral), the transformation was a horizontal translation.
If the change in x coordinate was such of from x to its opposite, then the transformation was that of a reflection around the y axis.

Answer:
(c) No, it is not a rectangle because the diagonals are not congruent
Step-by-step explanation:
The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...
AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5
BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5
The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:
No, it is not a rectangle because the diagonals are not congruent.
_____
The lengths are found using the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
It's C, the diagonals are not congruent (they aren't equal) and with rectangles they always have to be.
In a pet shelter that is occupied by 55% dogs and 45% cats, 60% of the animals are brought in by concerned people who found these
animals in the streets. If 90% of the dogs are brought in by concerned people, what is the percent of cats that are brought in by
concerned people?
Answer:
4.5%
Step-by-step explanation:
90% of the pets brought in by concerned people are dogs.
This means that the remaining 10% of pets brought in by concerned people are cats.
10% of 55% of cats is 4.5%
