Answer:
62°
Step-by-step explanation:
∠IKD=∠EIB=∠GJI =118° (Corresponding angles)
∠GJI+∠AJG=180° (Linear Pair)
∴∠AJG= 180°-118°
=62°
Answer:
n=48
Step-by-step explanation:
- add 48 to both sides to get rid of it
- 43+5=48
- n=48
Since the midpoint lies on the axis, both ends are therefore equidistant from the axis and are mirrors of each other so..
Q = (4,9)

Answer:
A = 4 units²
Explanation:
S(-5, -8), T(-3, -6), U(-6, -5)
Area of triangle given coordinates:
= 1/2 [x₁(y₂ - y₃) + x₂(y₃ - y₁) + x₃(y₁ - y₂)]
= 1/2 [-5(-6 - (-5)) + -3(-5 - (-8)) + -6(-8 - (-6))]
= 1/2 [5 - 9 + 12]
= 1/2 [ 8 ]
= 4
