Leto [7]3 years ago
3 0

Answer:

cos(71)

Step-by-step explanation:

Since 19° is less than 90, we can express this in terms of confunction.

sin(θ) = cos(90-θ)

sin(19) = cos(90-19)

sin(19) = cos(71)

rodikova [14]

Answer:

(a) 55.6%

(b) 45.0%

(c) 38.5%

(d) 27.1%

(e) 64

(f) 47

(g) The Lions

Step-by-step explanation:

(a) Free throw % for Lions is

\dfrac{10}{18}\times 100\% = 55.6\%

(b) Free throw % for Eagles is

\dfrac{9}{20}\times100\% = 45\%

(c) For the Lions, they attempted a total of 51 + 14 = 65 field goals and made 21 + 4 = 25.

Field goal % for Lions is

\dfrac{25}{65}\times100\% = 38.5\%

(d) For the Eagles, they attempted a total of 45 + 14 = 59 field goals and made 10 + 6 = 16.

Field goal % for Eagles is

\dfrac{16}{59}\times100\% = 27.1\%

(e) Total points by Lions = (10 × 1) + (21 × 2) + (4 × 3) = 10 + 42 + 12 = 64

(f) Total points by Eagles = (9 × 1) + (10 × 2) + (6 × 3) = 9 + 20 + 18 = 47

(g) The Lions won because they had more points.

3 is incorrect, should be 28.9

16^2 + 18^2 = EG^2
256 + 324
580 = EG^2
EG ≈ 24.08

16^2 + 24.08^2 = AG^2
256 + 580 = AG^2
836 = AG^2
AG ≈ 28.9

5 is incorrect:

The base is 8.
Draw an altitude the base.
Since the triangle is isoceles, it divides the base in half.
Half of that base is 4.
Two right triangles have been formed with one leg 4 and hypotenuse 8.
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b ≈ 6.93

The height of the triangle is 6.93, the base is 8.
A = bh/2 = 8*6.93/2 ≈ 27.7 ≈ 28
