Answer:
W - (-4,4)
X - (-1,4)
Y - (-1,2)
Z - (-4,2)
Step-by-step explanation:
hope it helps. :)
Answer:
first you subtract 5 from both sides
your left with 3x=11
divide by 3 on both sides
x=3.666 repeating

Answer:
The answer is B.It is one-half the area of a square of side length 4 units.
Step-by-step explanation:
Given a coordinate grid shown with triangle of measurements with base 4 units and height also 4 units.
We have to find the area of triangle which can be calculated as
⇒
=
we have to choose the statement describes the area of the triangle evaluate above.
Option A: Not matched ∵equals to [area of rectangle of length 4 units width 2 units]=
Option B: matched : given one-half the area of a square of side length 4 units.
⇒
Option C : Not matched : It is twice the area of a rectangle of length 4 units and width 2 units
⇒
Option 4 : Not matched : It is twice the area of a square of side length 4 units.
⇒
So, the correct option is B. It is one-half the area of a square of side length 4 units.
Answer:
Option D
Step-by-step explanation:
The questions which involve calculating the angles and the sides of a triangle either require the sine rule or the cosine rule. In this question, the two sides that are given are adjacent to each other and the given angle is the included angle. This means that the angle is formed by the intersection of the two lines. Therefore, cosine rule will be used to calculate the length of b. The cosine rule is:
b^2 = a^2 + c^2 - 2*a*c*cos(B).
The question specifies that a=42, B=120°, and c=35. Plugging in the values:
b^2 = 42^2 + 35^2 - 2(42)(35)*cos(120°).
Simplifying gives:
b^2 = 4459.
Taking square root on the both sides gives b = 66.78 (rounded to the two decimal places).
This means that the length of the third side is 66.78 units!!!
