Subtract 3 from the right and do the same to the left which leaves you to x = -1
Step-by-step explanation:
By Cosine rule, we have
s² = t² + u² - 2(t)(u)(cosS)
=> cosS = (t² + u² - s²)/2tu
=> cosS = (58² + 27² - 50²) / (2 * 58 * 27) = 0.5086.
Therefore S = cos^-1(0.5086) = 59.4° (1d.p.)
Answer:
Slope: Be inclined from a horizontal or vertical line; slant up or down. Slope formula is m=rise/run
Y-Intercept: The vertical axis represents a variable y, a y-intercept or vertical intercept is a point where the graph of a function or relation intersects the y-axis of the coordinate system.

Step-by-step explanation:
vertical angles are the opposite angles created by intersecting lines and are congruent. Vertical angles share only a vertex
