Answer:
hello,
Step-by-step explanation:
a)
In an isocele triangle, base's angles have the measure:
42+2a=180
2a=180-42
a=69(°)
b)
in a triangle, an external angle has for measure the sum of the angles not adjacents.
55+b=132
b=77 (°)
c)
in a quadrilater the sum of the (interior) angles is 2*180=360 degrees.
90+90+68+c=360
c=360-90-90-68
c=112 (°)
Answer:
x > 90, C
Step-by-step explanation:
20 + 2 < x / 3 - 8
x / 3 - 8 > 22
x / 3 > 30
x > 90
Answer:
23 decries up wards then move it down twice :)
Step-by-step explanation:
Answer:
rate of change is -3
A = (9 - 0) / (0 - 3) = 9 / -3 = -3
Step-by-step explanation:
90 degrees rotation about the origin
