Find x. Then find the measure of angles A, B and C.
mafiozo [28]

Answer:

x= 11

A=59

B= 37

C = 84

Step-by-step explanation:

A triangle adds up to 180 °.

So the equation will be a °+ b° + c° = 180°

Next, you combine like terms.

6x + 3x + 9x+4-15-7 = 180\\18x-18=180

Then inverse operation,

18x-18=180\\18x=198\\x=11

After to get a, b, and c you just need to plug in x.

6(11)-7=a\\3(11)+4 = b\\9(11)-15=c

Write the equation of a line in slope-intercept form that is parallel to the line y equals 7 over 8 x minus 7 and containing poi
STALIN [3.7K]

Answer:

y = (7/8)x + 7

Step-by-step explanation:

"7 over 8 x" is incorrect; you meant "(7/8)x" (which is not the same as "7 over 8 x."  Thus, your line is y = (7/8)x - 7.  The slope of a parallel line is the same, or (7/8).  Given that the line passes thru (8,0), we have enuf info with which to calculate the y-intercept.  Write out:  y = mx + b.  Immediately replace m with (7/8), y with 0 and x with 8, obtaining:  0 = (7/8)(8) + b.  Then b = 7, and the equation of this new, parallel, line is y = (7/8)x + 7.
