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°
It would be: k+3 = 10
subtracting 3 from both sides,
k+3-3 = 10-3
k=7
Answer:
Step-by-step explanation:
Puan Rohana's income = Active income + passive income
= 2000 + 450
= RM 2450
Expenses = 1680 + 400

Total expenses increased by 40%
New expenses after 40% increase = 2080 + 40% of 2080
= 2080 + (0.4 * 2080)
= 2080 + 832
= RM 2912
Puan Rohana's expenses is more than there income
Answer:

Step-by-step explanation:
You're looking for circumference here.
d = diameter of the wheel
d = 26 inches.
Input your values:
C = π * d
C = 3.14 * d
C = 3.14 * 26 inches
C = 81.64 inches.
