Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Subtract the constant on the left:
... (x +yi) = (9 -4i) -(4 +9i)
... = (9 -4 +i(-4-9))
... = 5 -13i
Matching real and imaginary parts, we see that ...
... x = 5, y = -13
Answer:
x = 92
Step-by-step explanation:
The segment of measure 46 joins the midpoints of 2 sides of the triangle and is one half the measure of the third side, thus
x = 2 × 46 = 92
Answer: If the question is to solve for A: A= 
If the question is to solve for B: B= 15x+1-3xA+A
Step-by-step explanation:
A: Move terms to the left.
B: Simplify both sides.

Answer:
y°= 51.30°
Step-by-step explanation:
Apply the formula for tangent of an angle
Tan Ф = opposite side length/adjacent side length
Tan y= 10/8
Tan y= 1.25
y° = tan⁻(1.25) = 51.34°
To the nearest tenth y°= 51.30°
