Please help me,please and thank you :)

Answer: 4

36.87 degrees

Step-by-step explanation:

The figure shown is a right angled triangle. It has three sides, one of which is the longest. The longest side is called the hypotenuse. Either of the shorter sides is called the opposite and the adjacent side(always the side carrying both the 90 degrees angle and the given angle).

Since the triangle is a right angled triangle,

We can apply Pythagoras theorem to get the opposite side.

Hypothenuse ^2 = opposite ^2 + adjacent ^2

5^2 = 4 ^2 + opposite ^2

opposite = √ 25 - 16

opposite = √9 = 3

Let the angle be # degrees,

Cos # = adjacent / hypothenuse

= 4/5 = 0.8

# = cos^-1 (0.8) = 36.87 degrees

Burt's grandparents started a savings account for him when he was born. They invested
SashulF [63]

Answer:

4594.76 USD will be in the account on Burt's 18th birthday.

Step-by-step explanation:

Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:

C = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t} (1)

Where:

C_{o} - Initial amount, measured in US dollars.

C - Current amount, measured in US dollars.

r - Annual interest rate, measured in percentage.

t - Time, measured in years.

If we know that C_{o} = 1250\,USD, r = 7.5 and t = 18, then the money in the savings account on Burt's 18th birthday is:

C = (1250\,USD)\cdot \left(1+\frac{7.5}{100} \right)^{18}

C = 4594.76\,USD

4594.76 USD will be in the account on Burt's 18th birthday.
