Answer:
-2/3x + y = -7
Step-by-step explanation:
So, y = 2/3x - 7 is the slope-intercept equation. Now, we need to turn it into the standard equation of a slope.
Standard equation --> Ax + By = C
y = 2/3x - 7
-2/3x -2/3x
----------------------
-2/3x + y = -7 --> this is your equation in standard slope form.
A triangle is 180 degrees. X+first length+second length=180. Then solve
Answer:
30.5
Step-by-step explanation:
Angle B = Angle D (Alt. Exterior)
61 = 2x
61/2 = 30.5
Step-by-step explanation:
BOTH TRIANGLES ARE SIMILAR BY THE AA SIMILARITY POSTULATE.
In first triangle:
Remaining angle = 180° - (70° + 30°)= 80°
In second triangle:
Remaining angle = 180° - (80° + 30°)= 70°
Hence, all the angles of first triangle are congruent to the corresponding angles of the second triangle.
Thus, both the triangles are similar by
THE AA SIMILARITY POSTULATE
