The diagram shows a right-angled triangle.
Otrada [13]

Answer:

h ≈ 9.9 cm

Step-by-step explanation:

By applying tangent rule for the given angle in the given right triangle,

tan(51°) = \frac{\text{Opposite side}}{\text{Adjacent side}}

tan(51°) = \frac{h}{8}

h = 8 × tan(51°)

h = 9.879

h ≈ 9.9 cm

Therefore, measure of side 'h' is 9.9 cm.

Inga [223]

Answer:

The interest After 6 years is $ 79.03  

Step-by-step explanation:

Given as :

The principal amount deposited in account = $ 700

The rate interest earn = 1.8 % per year

The Time period = 6 years

<u>From Compounded Method </u>

Amount = Principal × (1 +\dfrac{\textrm Rate}{100})^{\textrm Time

Or, Amount = $ 700 × (1 +\dfrac{\textrm 1.8}{100})^{\textrm 6

Or, Amount =  $ 700 × 1.018^{6}

Or, Amount =  $ 700 × 1.1129

∴ Amount = $ 779.03

Now , Interest = Amount - Principal

I.e Interest = $ 779.03 - $ 700 = $ 79.03

Hence The interest After 6 years is $ 79.03  ,  Answer
