Answer:

60ft^2

Step-by-step explanation:

Split the area into two large triangles, the right and the left.

The base for the triangle is 10ft+20ft =30ft and we know the height is 2.

Since A=bh*1/2, A = 30*2*1/2. This equals 30. since there are two of these large triangles and they are equal, just multiply the area by 30.

Answer:

Step-by-step explanation:

10×2=20÷2=10×2=20 goes for the two top ones

20×2=40÷2=20×2=40 goes for the two bottom ones

40+20=60 is the answer

Answer:

1136/295 cm

Step-by-step explanation:

Corresponding lengths of similar figures are proportional.

If we let the radius of the second cylinder be x,

x/6.4 = 7.1/11.8

x = 6.4(7.1/11.8) = 1136/295 cm

Reflecting over the x-axis in words and formula

Ksivusya [100]

Answer:

Formula: (x, -y), when reflecting over the x-axis you keep the x-value the same, but change the sign of the y-value. For example: You have the original coordinates (3, 5), and if you reflect it over the x-axis it’ll be (3, -5).

Let the no be x

Inequality given by

$\\ \sf\longmapsto 2(x-4)\leqslant -18$

Let's solve

$\\ \sf\longmapsto x-4\leqslant -9$

$\\ \sf\longmapsto x\leqslant -5$

Given a right triangle with a hypotenuse of 15 feet and a height of 6 feet, find the measurement of angle

Artist 52 [7]

Answer:

66.42° between height and hypotenuse

23.58° between base and hypotenuse

Step-by-step explanation:

Using the concept of cosine and sine, we know that cosine of an angle is equal to the adjacent divided by hypotenuse.

Similarly, sine of an angle is given by opposite divided by hypotenuse

Tangent is given by opposite divided by adjacent

In rhis case, we use cosine

$\theta=cos^{-1}(\frac {6}{15})=66.4218215217982\\\theta\approx 66.42^{\circ}$

Therefore, the angle between the hypotenuse and height is 66.42°

To find the angle between base and hypotenuse, since it is a right angle triangle then the other angle will be 90-66.42=23.58°
