Answer:
927.0 cm²
Step-by-step explanation:
Step 1: find Z
m < Z = 180 - (28 + 118) (sum of ∆)
= 180 - 146
Z = 34°
Step 2: Find side XY using the law of sines

Cross multiply


Divide both sides by 0.469


XY ≈ 50 cm
Step 3: find the area.
Area of ∆ = ½*XY*YZ*sin(Y)
XY ≈ 50 cm
= ½*50*42*sin(118)
= 25*42*0.8829
Area = 927.045
Area ≈ 927.0 cm² (nearest tenth)
Answer:
p = -2
Step-by-step explanation:
p − 10p + -5p + 14p − -9p − 2 = -20
-9p + 9p + 9p = -20 + 2
9p = -18
p = -2
