Answer:
B
Step-by-step explanation:
120+4x-12=180, 4x+108=180,4x=72, x=18
First, you have to imagine that you cut the upper triangle. If you do that, then this is how the inner angles are added to 180°:
180° = 90° + (x/2) + (7x - 90°)
180° = x/2 + 7x
180° = x *(1/2 + 7)
180° = x*(15/2)
2/15 * 180° = x
24 = x
Angle A:
A= x/2
A = 24/2
A = 12°
Angle B:
B = 7x
B = 7*24
B = 168°
The two bottom angles are both worth 90°.
Answer:
GH = (5, -3)
Step-by-step explanation:
The horizontal extent of the vector is 5 squares; the vertical extent is 3 squares. H has a lower y-value than G, so the vertical component is -3.
GH = (5, -3)
I would say the answer is B. 8 1/2 because 11/20 is close to 10/20 which would be the same as 1/2
Step-by-step explanation:
Yes, one pair of opposite sides could measure 10 inches. and the other pair could measure 13 inches
