Answer:
x = 16
m<R = 34°
Step-by-step explanation:
▪︎Its an isoceles triangle, so the two opposite angles are equal. m<S = <T.
▪︎So, you write them equal to each other and solve the linear equation to find <em>x</em><em>.</em><em> </em>
▪︎Substitute the x value into any of the angles and multiply by 2, (as they are equal) to find the sum, which is 146°.
▪︎Sum of all angles in a triangle is 180°,so
146° + m< R =180°
▪︎than minus 146° from 180°.
▪︎And you will have your answer.

Answer:
y = - 2x + 6
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (1, 4 ) and (x₂, y₂ ) = (2, 2 )
m = =
= - 2 , then
y = - 2x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 2 ) , then
2 = - 4 + c ⇒ c = 2 + 4 = 6
y = - 2x + 6 ← equation of line
