B is 2,2 A is -1,1 c is 2,-1
The platform is square. Let the length of one side be x.
Then the perimeter is P = 6x - 6 = 4x
Then 2x = 6 and x = 3. The side length is 3.
Check: P = 4(3) = 12
P = 6(3)-6 = 12
These agree.
The first one is 64, the second 250, the third 520, and the fourth is 96
Answer:
m∠2 = 118, and m∠3 = 31
Step-by-step explanation:
The 2 opposite angles of a rhombus are equal.
Angle 1 and Angle 2 are opposite to each other. Since Angle 1 is 118, angle 2 is also 118.
Now looking at the bottom triangle in the rhombus, the two sides are equal (given by 2 lines). Hence, the 2 opposite angles are equal. Since we know 3 angles of a triangle add up to 180 degrees, we can write: (let angle 3 be x):
x + x + 118 = 180
2x = 180 - 118
2x = 62
x = 62/2
x = 31
So m∠2 = 118, and m∠3 = 31
