Which of the following lines is perpendicular to the line 8x + 6y = 12 and passes through the point (-12,-2)?​

Answers

Answer:

y = 3/4x + 7

Step-by-step explanation:

8x + 6y = 12

6y = -8x + 12

y = -4/3x + 2

Perpendicular slope: 3/4

y - y1 = m(x - x1)

y + 2 = 3/4(x + 12)

y + 2 = 3/4x + 9

In the figure, angle D measures 31 degrees and angle A measures 27 degrees.
The measurement of angle B is:
59, 63, or 90
Angle F is:
59, 63, or 90​

Answers

Answer:

Angle B = 63° Angle F = 59°

Step-by-step explanation:

C = 90° (right angle)

A = 27°

3 angles are added to result in 180° (property of triangle)

Therefore B =

180 - (90 + 27) =

180 - 117 =

63°

Angle B = 63° ✅

E = 90° (right angle)

D = 31°

3 angles are added to result in 180° (property of triangle)

Therefore F =

180 - (90 + 31) =

180 - 121 =

59°

Angle F = 59° ✅

____________________

#IndonesianPride - kexcvi

Answer:

B= 63

F= 59

Step-by-step explanation:

a+ b+ c= 180

27+b+ 90=180

117+b=180

180-117=b

B= 63

D+E+F=180

31+ 90+ F=189

121 +F=180

180-121= F

F= 59

Answers

Answer:

m<1 = 97°

Step-by-step explanation:

<1 and 83° are same-side interior angles. Same-side interior angles are supplementary. This implies that:

m<1 + 83° = 180°

Therefore:

m<1 + 83° - 83° = 180° - 83° (subtraction property of equality)

m<1 = 97°

Answer:

<1=97°

steps:

<1+83=180 co interior angle

<1=180-83=97°

No congruent sides are shown.... That means it's a scalene.
