Step-by-step explanation:

5. θ = 60°

→ To find the value of y ,

Cos θ = b/h

<u>putting</u><u> </u><u>the </u><u>values </u><u>in </u><u>terms </u><u>of </u><u>cos</u>

Cos 60° = y/16

1/2 = y/16

16/2 = y

y = 8 unit

→ To find the value of x ,

Sinθ = P/h

<u>putting the values in terms of </u><u>sin</u>

Sin60° = x/16

√3/2 = x/16

16×√3/2 = x

16×1.73/2 13.84 unit

6. θ = 30°

→ To find the value of y

tanθ = p/b

<u>putting the values in terms of </u><u>tan</u>

tan 30° = 2/y

1/√3 = 2/y

2×√3 = y

3.46 unit = y

→ To find the value of x

Sin θ = p/h

<u>putting the values in terms of sin</u>

Sin 30° = 2/x

1/2 = 2/x

4 unit = x

Da sofa is on sale for $98.60, which is 29% of the regular price. What is the regular price ?
yaroslaw [1]
Let the regular price be X
x\98.60 x 100=29%
100x\98.60=29(multiply both sides by 98.60 to remove the denominator
100x=2859.4(divide both sides by 100
x=28.594
regular price=$28.594

The length of the base of a scalene triangle is 22 meters and the height is 14 meters. Find the area of the scalene triangle
Nezavi [6.7K]

Answer:

Area is 154 square meters

Step-by-step explanation:

Well lets think about this

If I take a rectangle and cut it into half diagonally I would get 2 triangles right?

So if I have 2 triangles of the same height and base I can make a rectangle

to find the area of a rectangle I do length times width

So lets take our scalene triangle and multiply our base with its width and then divide by 2

22*14 = 308

308/2 is 154

10. The sum of two numbers is 6 less than twice the first number. Their difference is 10 less than four times the second number.
Ilya [14]

Answer:

10 and 4.

Step-by-step explanation:

Let x be the first number.

Let y be the second number.

x + y = 2x - 6

x - y = 4y - 10

x = 4y - 10 + y

x = 5y - 10

(5y - 10) + y = 2(5y - 10) - 6

6y - 10 = 10y - 20 - 6

6y - 10 = 10y - 26

6y - 10y = -26 + 10

-4y = -16

y = 4

x - (4) = 4(4) - 10

x - 4 = 16 - 10

x - 4 = 6

x = 6 + 4

x = 10

Oliga [24]
I don't have my calculator handy just now. But just looking at that problem, why don't you try +20 and -45 and see if they do the job.
