∠A and \angle B∠B are complementary angles. If m\angle A=(2x+30)^{\circ}∠A=(2x+30)

and m\angle B=(6x-12)^{\circ}∠B=(6x−12)

, then find the measure of \angle A∠A..

Answers

Answer 1

Answer:

∠A = 48

Step-by-step explanation:

∠A + ∠B = 90   ( Complementary angles)

2x + 30 + 6x - 12 = 90

Combine like terms

2x + 6x +30 - 12 = 90

              8x  + 18 = 90   {subtract 18 form both sides}

                       8x = 90 - 18

                      8x = 72  {Divide both sides by 8}

                  8x/8 = 72/8

x = 9

∠A = 2x + 30

     = 2*9 + 30

     = 18 + 30

∠A = 48

Answer:

You have to go clockwise and 90 degrees and the rest is self explanatory. Hope I helped.

Step-by-step explanation:

The required transformation of the polygons ABCD to  A'B'C'D'  is 7 units right and a clockwise orientation.


Given that,
Each graph shows two polygons ABCD and A'B'C'D'. In each case, To describe a sequence of transformations that takes ABCD to A'B'C'D'.

What is a polygon?

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of the polygon, equilateral triangle, square, pentagon etc

Here,
Polygons ABCD is at the left side of the y-axis and after transformation is shifted to the right of the y-axis by 7 units as the Location of Point A and the Location of point B' is 7 units apart. And is also oriented to 90° clockwise.

Thus, the required transformation of the polygons ABCD to  A'B'C'D'  is 7 units right and a clockwise orientation.

Make use of the difference of squares identity,

Let [tex]a=\sqrt5-\sqrt7[/tex] and [tex]b=\sqrt{12}[/tex]. Then

[tex]\dfrac1{(\sqrt5-\sqrt7)+\sqrt{12}}\cdot\dfrac{(\sqrt5-\sqrt7)-\sqrt{12}}{(\sqrt5-\sqrt7)-\sqrt{12}}=\dfrac{(\sqrt5-\sqrt7)-\sqrt{12}}{(\sqrt5-\sqrt7)^2-(\sqrt{12})^2}=\dfrac{\sqrt5-\sqrt7-\sqrt{12}}{5-2\sqrt{35}+7-12}=-\dfrac{\sqrt5-\sqrt7-\sqrt{12}}{2\sqrt{35}}[/tex]

Answers

Answer:

The answer is 43 meters below the water.
