Answer:

59°

Step-by-step explanation:

From the diagram, shown in the attachment line x and y are parallel lines.

Angle 7 and angle 6 are angles on a straight line.

The two angles will add up to 180 degrees.

\angle 7+\angle 6=180

But angle 7 measures 121°.

This implies that:

121+\angle 6=180

Solve for angle 6 to get;

\angle 6=180-121\

\angle 6=59\degree

Find the value of x - Step by step answer please
Ugo [173]

Answer:

x = -2

Step-by-step explanation:

Given :

\frac{8}{x+1} = \frac{-16}{x+4}

=============================================================

Cross multiplying the terms :

⇒ 8 (x + 4) = -16 (x + 1)

⇒ 8x + 32 = -16x - 16

⇒ 24x = -48

⇒ x = -2
