Find x and y part 4 for these problems​

Mathematics
1 answer:
Dvinal [7]3 years ago
6 0

Answer:

Step-by-step explanation:

3) Sin30 = 11/x

x = 11/Sin30 = 11/0.5

x = 22

Tan 30 = 11/y

y = 11/tan30 = 11/0.5774

y = 19.1

4) Sin30 = 6/x

x = 6/Sin30 = 6/0.5

x = 12

Tan 30 = 6/y

y = 6/tan30 = 6/0.5774

y = 10.39

5) Sin45 = 9√2/y

y = 9√2/Sin45 = 9√2/(√2/2) =

9√2 × 2/√2 = 18

x = 18

Tan 45 = 9√2/x

x = 9√2/Tan 45 = 9√2/1

x = 9√2

6)

Sin60 = 9/x

x = 9/Sin60 = 9/0.866

x = 10.39

Tan 60 = 9/y/2 = 18/y

1.7321 = 18/y

y = 18/1.7321

y = 10.39

The correct answer is 25 square units

Explanation: The equation for finding the area of a triangle is base times height divided by 2. So the base is 10 and height is 5. So the equation would be 10x5=50/2=25 square units. Therefore, your correct answer is 25 square units.

Also, I would really appreciate brainliest. Hopefully this helps and good luck.

A kilogram of whole-wheat flour costs $6. What is the cost of 400 grams of flower
Hitman42 [59]
1 \ kg=1000 \ g \ - \ \$6 \\
400 \ g \ - \ x \\ \\
\frac{1000}{6}=\frac{400}{x} \\
1000x=400 \times 6 \\
1000x=2400 \\
x=\frac{2400}{1000} \\
x=2.4

400 grams of flour cost $2.4.
