kenny6666 [7]

Answer:

The height of the tree is 64.94\ ft

Step-by-step explanation:

Let

y ----> the height of the tree

we know that

tan(33\°)=y/100 ----> the function tangent is equal to divide the opposite side angle of 33 degrees by the adjacent side angle of 33 degrees

Solve for y

y=(100)tan(33\°)=64.94\ ft

A. 207.5ft
julia-pushkina [17]

Law of cosines:

a^2 = b^2 + c^2 -2 *b*c*coa(a)

a^2 = 60.5^2 + 257^2 - 2*60.5*257*cos(31)

a^2 = 3660.25 + 66049 - 2 *60.5 * 257 * 0.857167

a^2 = 3660.25 + 66049 - 26655.33

a^2 = 43053.92

a = SQRT(43053.92)

a = 207.49 = 207.5 feet.


The answer is A.

Marcel bought a new hat for $21.99 and 2 pairs of socks for $3.99each. What is the total price, including a 7.5% sales tax?
NNADVOKAT [17]

Cost of a hat bought by Marcel = \$ 21.99

Cost of a pair of socks = \$ 3.99

Cost of 2 pair of socks =2 \times 21.99 = \$ 7.98

Total price of hat and two pair of socks = \$ (21.99 + 7.98) = \$ 29.97

A sales tax of 7.5 \% on this purchase = 7.5 \%  \times \$29.97

=\frac{7.5}{100} \times 29.97 = \$2.25

Therefore, the total price including the sales tax = \$ 29.97 + \$ 2.25

=\$ 32.22
