Answer:

Option A

10.5 m²

Step-by-step explanation:

The area of a triangle is half the product of its base by its height.

A = 0.5bh

Where b is the base and h is the height.

In this triangle b = 6.1 m.

The height of this triangle is a line perpendicular to its base that goes to the vertex opposite the base.

We do not know this length. But this line h divides the triangle into two rectangular triangles.

So for these two triangles the angle that is opposite to the height h is: 47 °

Therefore we know that senx is defined as:

senx =\frac{opposite side}{hypotenuse}

Where:

Opposite side = h

hypotenuse = 4.7 m

x = 47

Sin(47) = \frac{h}{4.7}\\\\h = (sin47)(4.7)\\\\h = 3.437

Finally, the area is:

A = 0.5(3.437)(6.1)\\\\A = 10.5m^2

Answer:

option A

10.5 m²

Step-by-step explanation:

Given in the question,

base of triangle = 6.1 m

one side of triangle = 4.7m

one angle = 47°

To find the area of this triangle we will use the following formula

<h3>Area = 1/2 (height)(base)</h3>

Step1

Find height by using trigonometry identity

sinФ = opp/hyp

sin(47) = height/4.7

height = 3.44m

Step2

Plug values in the formula of area

(0.5)(6.1)(3.43)

10.48m²

≈10.5m²

Answer:

C. y= 6x-5

Step-by-step explanation:

Given Information :

Slope (m) = 6

y-intercept (b) = -5

Equation of a line :

y=mx+b

Where :

m = slope

b = y-intercept

So , with the given the information , the equation is :

Please help <br> 2y+x=-15 <br> y=2x
Eva8 [605]

Answer: x = -3

Step-by-step explanation:

2y + x = -15

y = 2x

2y = 2(2x) = 4x

4x + x = -15

5x = -15

x = -3
