Answer:
∠ 1 = 123°
Step-by-step explanation:
One way
The external angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 1 is an external angle of the triangle, thus
∠ 1 = 90° + 33° = 123°
Second way
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for third angle in Δ
third angle = 180° - (90 + 33)° = 180° - 123° = 57°
The third angle and ∠ 1 form a straight angle and are supplementary, thus
∠ 1 = 180° - 57° = 123°
The interest rate will be equal to 24% in 2 years.
<h3>What is compound interest?</h3>
Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-
Given that:-
- Find the interest rate if $32 increased to $50 in 2 years.
The interest rate will be calculated by using the following formula:-
![A = P[1+\dfrac{r}{n}]^{nt}](https://tex.z-dn.net/?f=A%20%3D%20P%5B1%2B%5Cdfrac%7Br%7D%7Bn%7D%5D%5E%7Bnt%7D)
![50=32[1+\dfrac{r}{1}]^{2}](https://tex.z-dn.net/?f=50%3D32%5B1%2B%5Cdfrac%7Br%7D%7B1%7D%5D%5E%7B2%7D)

1.56 = ( 1 + r )²
√1.56 = ( 1 + r )
r = 1.24 - 1
r = 0.24
r = 24%
Therefore interest rate will be equal to 24% in 2 years.
