Answer:
1 and 8
2 and 7
Step-by-step explanation:
Alternate angles take form of a Z-angle.
For alternate exterior angles look for exterior angles that for Z- pattern.
The alternate exterior angles are marked in the attached diagram.
Hence the alternate exterior angles are:
1 and 8
2 and 7
If any line drawn from center of the circle (OC in the diagram) bisect the chord of circle (AB in the diagram), then it is said to be perpendicular to chord AB.
So OC is perpendicular to CB, and we can say that triangle OCB is the Right Triangle.
In the Right Triangle OCB,
angle BCO = 90°
angle COB = 90° - angle CBO = 90° - 40° = 50°
So, option A is the final answer, 90° and 50°.
Answer:
Rs 253.13
Step-by-step explanation:
The item cost him x.
Selling at a profit of 20% means he sold it for 1.2x.
Selling at a loss of 12% means that he sold it for 0.88x.
1.2x - 81 = 0.88x
1.2x - 0.88x = 81
0.32x = 81
x = 253.13
Answer: -2y < -20
Step-by-step explanation:
Hello :
let : x this number
10√x = 40 x ..... x <span>> 0
</span>√x = 4 x and : x > 0
(√x )²= (4 x)² and : x > 0
x = 16 x² ....x > 0 : i'can simplifiy by : x
1 =16x
x = 1/16
