Answer:
x= -18.16 x= -11.84
Step-by-step explanation:
(x+15)(x+15)= x^2+30x+225-10=0
x^2+30x+215=0
a=1 -30±√(30)²-4(1)(215)
b=30 -----------------------------
c=215 2(1)
We know that cos A = 0.34.
We have to find the measure of ∠ A in degrees ( and to round it to the nearest hundredth ):
∠ A = cos^(-1) 0.34 = 70.12313° ≈ 70.12°
Proof: cos 70.12° ≈ 0.34
Answer:
∠ A = 70.12°
Area: 126ft

Answer:
A. Sharon spent $10 to buy 25 water bottles at Randolph's Grocery
Step-by-step explanation:
