Angle 1 and angle 2 are vertical angles. If m angle 1 = (8x+12)° and m angle 2 = (3x+37)° find the measure for each angle.

laila [671]

Vertically opposite angles are always equal.

Given angles are (8x+12)° and (3x+37)°

=> (8x+12)° = (3x + 37)°

=> 8x - 3x = 37-12

=> 5x = 25

=> x = 25/5 = 5°

Angle 1 = (8x+12)° = (8(5)+12) = 40+12 = 52°

Angle 2 = (3x + 37)° = (3(5)+37)° = 15+37 = 52°

Answer ASAP!!!!!!! Segment BDSegment BD is a perpendicular bisector of segment ACsegment AC . AD=9x+3AD=9x+3 and DC=57DC=57 .

sergey [27]

AD = 9x + 3

DC = 57

ADC is a line, which is perpendicularly bisected by BD.

Thus AD = DC

9x + 3 = 57

9x = 57 – 3

9x = 54

x = 54/9

x = 6

Write an equation for the line parallel to the given line that contains C. C (1,8); 5/7x + 7

Answer: $\textsf{y = 5/7x + 51/7}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}$

Find: $\textsf{Write an equation that follows that criteria}$

Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7. We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.

Plug in the values
