Answer:

a = 11

Step-by-step explanation:

if A is 7 in the equation A + 4, the it could also be written as 7 + 4.

then it would just be simple addition, because you would add 7 + 4, which equals 11.

Hope this helps!

  • Distance Formula: \displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

Point (-1, -8)

Point (-4, -4)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(-4--1)^2+(-4--8)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                   \displaystyle d = \sqrt{(-3)^2+(4)^2}

  4. [√Radical] Add:                                                                                                 \displaystyle d = \sqrt{25}
  5. [√Radical] Evaluate:                                                                                           \displaystyle d = 5

Can someone help me on this math problem.
nekit [7.7K]

In the rhombus, the diagonals are perpendicular.

We know, the sum of the measures of the triangle is equal 180°.

Therefore we have the equation:

(2x-15)+3x+90=180

2x-15+3x+90=180        <em>combine like terms</em>

(2x+3x)+(-15+90)=180

5x+75=180        <em>subtract 75 from both sides</em>

5x=105              <em>divide both sides by 5</em>

\boxed{x=21}

<h3>Answer: x = 21°</h3>
