SOMEONE HELP! I know the answer I just need to show the work.
gayaneshka [121]

okay so

117° + angle a = 180° (supplementary angle)

angle a = 180 - 117

= 63°

then angle a + angle b + 81° = 180° ( angle sum property)

so... 63° + angle b + 81° = 180

144 + angle b = 180°

angle b = 180 - 144

= 36°

hope this helps.

Find the equation of the linear function 'g' going through (20,5) and (-5,-8). Use 'u' for your input variable.
frosja888 [35]

Answer:

  • See below

Step-by-step explanation:

<u>Use the slope-intercept form, which will be in this case:</u>

  • g(u) = mu + b, where m is the slope, b is the y- intercept

<u>Find the slope:</u>

  • m=(y_2-y_1)/(x_2-x_1)
  • m=(-8-5)/(-5-20)=(-13)/(-25)=13/25

<u>Find the value of the y-intercept:</u>

  • 5=1/25*20+b
  • b=5-4/5=21/5

<u>The equation is:</u>

  • g(u)=\frac{13}{25} u+\frac{21}{5}
