Answer:

44.2545

Step-by-step explanation:

you can find the third angle by taking 180-(90+55)=a

a=35

use law of sines

Sin(angle)/(opposite side of angle)=Sin(another angle)/(opposite side of another angle)

so, sin(a)/A=sin(b)/B

sin(35)/33=sin(55)/x

x=sin(55)/(sin(35)/33)

x=44.2545

Hope this helps :)

The difference between the square of two numbers is 11. Twice the square of the first number increased by the square of the seco
jeyben [28]

Answer:

Below in bold.

Step-by-step explanation:

x^2 - y^2 = 11

2x^2  + y^2 = 97

From the first equation:

y^2 = x^2 - 11

Substituting in the second equation:

2x^2 + x^2 - 11 = 97

3x^2 = 108

x^2 = 36

x = 6, -6.

Substituting  for x in the first equation:

(6)^2 - y^2 = 11

y^2 = 36 - 11 = 25

y = 5, -5.

please help: What is the equation of a line parallel to -5x + y= 2 that passes through the point with coordinates (-2, 1)?
weqwewe [10]

Answer:

  • y = 5x + 11 or -5x + y = 11

Step-by-step explanation:

<u>Given line:</u>

  • -5x + y = 2

<u>In slope-intercept form:</u>

  • y = 5x + 2

<u>The parallel line has the same slope and will look as:</u>

  • y = 5x + b

<u>This line passes through the point (-2, 1), substitute:</u>

  • 1 = 5*(-2) + b
  • b = 1 + 10
  • b = 11

<u>So the line is:</u>

  • y = 5x + 11

or

  • -5x + y = 11
