Answer:
x = 36°
Step-by-step explanation:
interior angle of regular pentagon: 180 x (5-2) /5 = 540 / 5 = 108
∠C = 108
CD = CB ∠CDB = ∠CBD = (180 - ∠C) /2
x = (180 - 108) / 2 = 36°

Answer:
12.1 years
Step-by-step explanation:
We are given that
Principal amount, P=$3000
Rate of interest, r=6.75% semi-annually
Amount, A=$6700
We know that
When r pays semi-annually

Where n=2
Using the formula



Taking ln on both sides we get
