Answer:

5.) 39

6.) 52

Step-by-step explanation:

5.) 90-51= 39

6.) 74 + 34= 108

180-108= 72

56+72= 128

180-128= 52

Plzzzz help me on this questions fast <br><br>This is Trigonometry

Sladkaya [172]

Answer:

x ≈ 20.42, y ≈ 11.71

Step-by-step explanation:

Using the cosine ratio on the right triangle on the right, that is

cos20° = $\frac{adjacent}{hypotenuse}$ = $\frac{11}{y}$

Multiply both sides by y

y × cos20° = 11 ( divide both sides by cos20° )

y = $\frac{11}{cos20}$ ≈ 11.71

Using the sine ratio on the right triangle on the left, that is

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{y}{x}$ = $\frac{11.71}{x}$

Multiply both sides by x

x × sin35° = 11.71 ( divide both sides by sin35° )

x = $\frac{11.71}{sin35}$ ≈ 20.42

10. What is the distance between (8,7) and (3,-5)?

Anarel [89]

Answer:

distance between points=13 units

Step-by-step explanation:

distance between points= $\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

put $(x_1,x_2)$ =(8,7) and $(y_1,y_2)$ =(3,-5)

distance between points= $\sqrt{(3-8)^2+(-5-7)^2}$

distance between points= $\sqrt{(-5)^2+(-12)^2}$

distance between points= $\sqrt{25+144}$

distance between points= $\sqrt{169}$

ASK YOUR TEACHER Two streets meet at an 84° angle. At the corner, a park is being built in the shape of a triangle. Find the are

Alla [95]

Answer:

22,203 ft^2

Step-by-step explanation:

The area of a triangle with angle ∅ and two sides a and b is;

Area A = 1/2 × absin∅ ......1

The park is in the shape of a triangle, with two sides and an angle given;

Given;

a = 190 ft

b = 235 ft

∅ = 84°

Substituting the values into equation 1;

Area of the park;

A = 1/2 × 190 × 235 × sin84°

A = 22,202.70131409 ft^2

A = 22,203 ft^2 (to the nearest whole number)

Area of the park is 22,203 ft^2
