Answer: the length of the side of the house is 14.9 yards
Step-by-step explanation:
The shape of the foundation of the new home that Mr. and Mrs. Phillips are going to build is square.
The formula for determining the area of a square is
Area of square = L^2
Where
L represents the length of each side of the square.
The house will cover 222 square yards. It means that the length of the side of the house would be
√222 = 14.8997
Approximating to the nearest tenth, it becomes 14.9 yards
A + s = 279
s = 2a
a + 2a = 279
3a = 279
a = 279/3
a = 93 <=== adult
s = 2a
s = 2(93)
s = 186 ....students
Answer:
y=33 degree
Step-by-step explanation:
y = 33 degree (the relation between y and 33 is they are vertically opposite angles anf verticelly opposite angles are always equal)
Answer: Choice C
x/w and z/(y+v)
======================================================
Explanation:
All answer choices have that first fraction with a denominator of w. This implies that AB = w is the hypotenuse. This only applies to triangle ABD.
Focus on triangle ABD. It has an opposite leg of AD = x, when the reference angle is ABD (or angle B for short).
So we can say sin(ABD) = opposite/hypotenuse = AD/AB = x/w
x/w is one of the answers
-----------
Also note how y+v is the same for each denominator in the second fraction. y+v is the hypotenuse of triangle ABC. When the reference angle is ABD (aka angle ABC), the opposite side of this same triangle is AX = z
Therefore,
sin(ABD) = sin(ABC) = opp/hyp = AC/BC = z/(y+v)
z/(y+v) is the other answer
Side note: triangle ACD is not used at all.
Answer:
B and E
Step-by-step explanation:
Fit's, they multiplied both sides by 4/3 instead of 3/4. Then they divided the answer by 3 instead of taking the cube root of both sides.
