∠1 and ∠2 are complementary angles.

Roman55 [17]

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

In the given question, the two angles are complementary Angle pair, so the sum of their values will add up to 90°

that is ~

$\qquad \sf \dashrightarrow \: (3x + 30) \degree + x \degree = 90 \degree$

$\qquad \sf \dashrightarrow \: 3x + x + 30 \degree = 90 \degree$

$\qquad \sf \dashrightarrow \: 4x = 90 \degree - 30 \degree$

$\qquad \sf \dashrightarrow \: 4x = 60 \degree$

$\qquad \sf \dashrightarrow \: x = 60 \div 4$

$\qquad \sf \dashrightarrow \: x = 15 \degree$

The equation of line WX is 2x + y = −5. What is the equation of a line perpendicular to line WX in slope-intercept form that con

borishaifa [10]

Answer: $y=\dfrac12x-\dfrac{3}{4}$

Step-by-step explanation:

Given, The equation of line WX is 2x + y = −5.

It can be written as $y=-2x-5$ comparing it with slope-intercept form y=mx+c, where m is slope and c is y-intercept, we have

slope of WX = -2

Product of slopes of two perpendicular lines is -1.

So, (slope of WX) × (slope of perpendicular to WX)=-1

$-2\times\text{slope of WX}=-1\\\\\Rightarrow\ \text{slope of WX}=\dfrac{1}{2}$

Equation of a line passes through (a,b) and has slope m:

$y-b=m(x-a)$

Equation of a line perpendicular to WX contains point (−1, −2) and has slope $=\dfrac12$

$y-(-2)=\dfrac{1}{2}(x-(-1))\\\\\Rightarrow\ y+2=\dfrac12(x+1)\\\\\Rightarrow\ y+2=\dfrac12x+\dfrac12\\\\\Rightarrow\ y=\dfrac12x+\dfrac12-2\\\\\Rightarrow\ y=\dfrac12x-\dfrac{3}{4}$

Equation of a line perpendicular to line WX in slope-intercept form that contains point (−1, −2) $:y=\dfrac12x-\dfrac{3}{4}$
