in triangle pqr, if angle p=x-12, angle q=5x-27, and angle r=2x+3, find c and the measure of each angle
SVEN [57.7K]

Answer:

8) x = 27

Angle P = x - 12 (15)

Angle Q = 5x - 27 (108)

Angle R = 2x + 3 (57)

Equation: (x - 12) + (5x - 27) + (2x + 3) = 180

x = 27

9) x = 14

Angle A = 7x - 6 (92)

Angle B = 3x - 5 (37)

Angle C = 4x - 5 (51)

Equation: (7x - 6) + (3x - 5) + (4x - 5) = 180

x = 14

10) x = 20

Angle K = x (20)

Angle L = x + 13 (33)

Angle J = 6x + 7 (127)

Equation: x + (x + 13) + (6x + 7) = 180

x = 20

11) x = 41

Angle Y = x (41)

Angle W = 2x - 5 (77)

Angle X = x + 21 (62)

Equation: x + (2x - 5) + (x + 21) = 180

x = 41

lana [24]

Answer:

Trace a line between the intersection of the two circles.

Step-by-step explanation:

This is a very important technique, the next thing you do is trace a line in between the intersection of the circles and that would intercept your circle. I will show you in a drawing.

Solve this quadratic equation using the quadratic formula. 5 - 10x - 3x2 = 0
horsena [70]

Answer:

x = (-5 ± 2√10) / 3

Step-by-step explanation:

5 − 10x − 3x² = 0

Write in standard form:

-3x² − 10x + 5 = 0

Solve with quadratic formula:

x = [ -b ± √(b² − 4ac) ] / 2a

x = [ -(-10) ± √((-10)² − 4(-3)(5)) ] / 2(-3)

x = [ 10 ± √(100 + 60) ] / -6

x = (10 ± 4√10) / -6

x = (-5 ± 2√10) / 3
