Answer:94°
Step-by-step explanation:
The sum of the interior angles of the polygon: 180°(n-2)
180°(5-2)=540°
The sum of the interior angles of the pentagon is 540°
So:
P+Q+R+S+T=540°
(4x+2)°+132°+(4x-10)°+(5x-11)°+128°=540°
4x+2+4x-10+5x-11+260=540
13x=299
x=23°
P=4x+2°=4×23°+2°=94°
Answer:
Given : s||t
Exterior sides in opposite rays : ∠5 and ∠7 are supplementary
Definition of supplementary angles : m∠5 + m∠7 = 180°
If lines are ||, corresponding angles are equal : m∠1 = m∠5
Substitution : m∠1 + m∠7 = 180°

Answer:
Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
Step-by-step explanation:
Given:
Slope = 2 = m ( say )
Let,
point A( x₁ , y₁) ≡ ( 10 , 17 )
To Find:
Equation of Line AB =?
Solution:
Equation of a line passing through a points A( x₁ , y₁) and having slope m is given by the formula,

Substituting the given values in a above equation we get

Therefore the equation of the line has a slope 2 and passes through ( 10 , 17 ) is
2x - y = 3
