Area of the upper rectangle = x(16 - 6) = 10x yd²

Area of the bottom rectangle = 6(x + 6) = 6x + 36 yd²

Total area = 10x + 6x + 36 = 16x + 36 yd²

Use trigonometry to find the value of angle C. Round your answer to the nearest whole number.

Art [367]

Answer: B

Step-by-step explanation:

To find angle C, you want to look at 14 and 16. From angle C, we have $tanC=\frac{opposite}{adjacent}$ . This tells us to use tangent. We use the values to fill into tangent.

$tanC=\frac{14}{16}$

In order to find the value of C, we have to find inverse tangent.

$tan^-^1(\frac{14}{16} )=C$

$C=41.2=41$

Given: 8x-61=17, prove: 39/4

Degger [83]

Answer:

The solution is $x = \frac{39}{4}$

Step-by-step explanation:

We are given the following equation:

8x - 61 = 17

We want to find the solution, that is, the value of x. So

$8x - 61 = 17$

$8x = 78$

$x = \frac{78}{8}$

Simplifying by 2

$x = \frac{39}{4}$

The solution is $x = \frac{39}{4}$

What is the order of rotational symmetry for a rhombus?

Ulleksa [173]

Answer:

Step-by-step explanation:

The order (or degree) of rotational symmetry of a rhombus is 2. This is because it looks the same only when rotated 0° or 180° (2 angles, total).
