Answer:
x = 10/27
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
9/5x = 2/3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide both sides by 9/5: x = 10/27
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 9/5(10/27) = 2/3
- Multiply: 90/135 = 2/3
- Simplify: 2/3 = 2/3
And we have our final answer!
(-5+8*i)+(-9+5*i) evaluates to <span>-14+13i</span>
<h3>The measure of smallest angle is 36 degrees</h3><h3><u>Solution:</u></h3>
Given that,
The angles of a triangle are in an extended ratio of 5 : 7 : 3
Let one of angle be 5x
Let the other angle be 7x
Let the third angle be 3x
We know that,
Sum of angles in triangle is 180 degrees
Therefore,
5x + 7x + 3x = 180
15x = 180
Divide both sides by 15
x = 12
<em><u>Thus the angles are:</u></em>
5x = 5(12) = 60
7x = 7(12) = 84
3x = 3(12) = 36
Thus the measure of smallest angle is 36 degrees
Answer:
16 - (4 × 3) + 7
Step-by-step explanation:
Answer:
y = 48°
Step-by-step explanation:
angle A = 90°
interior angles of a triangle = 180°
therefore
y = 180 - 42 - 90
y = 48°
