Answer:
the slope is 1/3
Step-by-step explanation:
y-2=1/3 * (x+0)
4x + 8y = -24
- 4x - 4x
8y = -4x - 24
8 8
y = ⁻¹/₂x - 3
Answer:
x = 6, y = 45
Step-by-step explanation:
C) The 2 triangles are similar , then we can write:
5x/45 = 20/36 . Cross multiplication:
5x*36 = 45*20
180x = 900 and x = 900/180 , x = 5 (and 5x = 25)
d) Remember the proportionality theorem (or Thales')
You can write the following proportion:
GH/HJ = KL/LM
8/6 = 10/x . Cross multiplication:
8x = 60 and x = 60/8 , x = 7.5
The answer
3. measure of DEA is 43°
proof: 90° +47° + mDEA= 180°, so mDEA= 43°
2.complementary angle
1.corresponding angles
