Answer:
Step-by-step explanation:
11 no
46+4x=90 degree(being perpendicular)
4x=90-46
x=44/4
x=11
12 no
They are complementary angles
6 no
angle B+27=180 degree(being straight line)
angle B=180-27
angle B=153
10 no
angle 38 +angle DFE=180 degree(being supplementary)
angle DFE=180-38
angle DFE=142 degree
5 no
They are vertically opposite angles.
7 no
angle AGF and angle CGD (because they have common arm and vertex)
Answer:
See below
Step-by-step explanation:
I'm not sure if there are any specific instructions on how these answers are supposed to be written, but here's my best shot:
1. U
2. XZ, VY
3. VU, WU
4. XY, ZY
5. ⊙U
6. XZ, VY (they are diameters but also intersect)
7. VY = 10 cm, WU = 5 cm
8. Diameter (of larger circle)
9. Diameter (of smaller circle)
10. Radius (of larger circle)
11. Radius (of smaller circle)
Answer:
x=2
Step-by-step explanation:
After solving with substitution, you would know x = 2
It should be -16, assuming you are asking for -4*4. If you meant -4^4 (-4 to the fourth power) then the answer is 256.
