What are the measures of Angles a, b, and c? Show your work and explain your answers. 400
a
650

Step-by-step explanation:

angle a=40 degree (being vertically angles)

angle a + 90 +angle b=180 degree (being sum of interior angles of a triangle)

40 +90 +angle b=180

130 + angle b=180

angle b=180-130

angle b =50 degree

vrtically opposite of angle b

vertically opposite of angle b + missing angle=65 degree (sum of two intrior opposite angle is equal to the exterion anle formed)

40 degree + missing angle=65

missing angle=65-40

missing angle=25 degree

angle c+ vertically opposite of angle b + missing angle=180 degree (being sum of interior angles of a triangle)

angle c +50 +25 =180

angle c+75=180

angle c=180-75

angle c=105 degree

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
