Answer: 0.05%
-------------------------------------------
Work Shown:
To go from percent form to decimal form, move the decimal over 2 spots to the left. Think of 2% as 2.0%
2% = 0.02
2.5% = 0.025
Multiply the decimal form of each percentage
0.02*0.025 = 0.0005
Convert that result to a percentage. Move the decimal 2 spots to the right
0.0005 = 0.05% is the probability both break down
Note: This multiplication rule only works if the two events are independent.
Answer:
68°
Step-by-step explanation:
As BA⊥BD, so ∠ABD = 90°
also, ∠ABD = ∠CBD + ∠ABC
⇒ 90° = 4x + 52° + 8x - 10°
⇒ 12x = 48°
⇒ x = 4°
now,
∠CBD = 4x + 52°
= 4(4°) + 52°
= 68°
