The measure of an angle is 8 degrees less than three times the measure of another angle. If the two angles are supplementary, wh

OLga [1]

Let x and y be the angles
X= 3•y-8
X+ y = 180
Substitute first relationship in second
3y-8+y=180
4y=180+8
Y =188/4= 47 degrees
X= 180-47=133 degrees
The measure of the large angle is
133 degrees

Answer to this question

Darina [25.2K]

Answer: The height of the rectangle is 8 centimeters (cm)

How?

A(rea) = B(ase) × H(eight)

Since the question gives us the formula (A = B × H), area (120 cm), and base (15 cm), it fills in some parts of the equation.

So really:

120 = 15 × H <-- This is the formula, but some parts are filled in

Which can be rearranged as:

H = 120 ÷ 15 <-- Solve this

H = 8

Hope this helps.

someone pls help meeeee!!!!!!<br>

Step-by-step explanation:

y = y

x - 2 = 2x - 3 - 3x²

3x² + x - 2x = - 3 + 2

3x² - x = - 1

a = 3, b = -1, c = 0

$\sf{x = \frac{-b \pm \sqrt{b^{2} - 4ac} }{2a} }$

$\sf{x = \frac{- (-1) \pm \sqrt{-1^{2} - 4 (0)} }{2(3)} }$

$\sf{x = \frac{ 1 \pm \sqrt{1 - 0} }{6} }$

$\sf{x = \frac{ 1 \pm \sqrt{1} }{6} }$

$\sf{x = \frac{ 1 + 1 }{6} }$

$\sf{x = \frac{ 2 }{6} }$

$\sf{x = \frac{ 1 }{3} }$

Substitution :

y = x - 2

y = ⅓ - 2

y = ⅓ - 6/3

y = - 5/3

y = - 1 ⅔
