Answer: C) exactly one triangle
<u>Step-by-step explanation:</u>
Given: ∠A = 45°, ∠B = 65°, side c = 4 cm
By the Triangle Sum Theorem, ∠C = 70°
Now you have a proportion so you can use the Law of Sines to find the exact length of side a and of side b.

Thus, there is exactly one triangle.
If each bracelet is $7 then you just need to multiply $7 by the number of bracelets you want to buy. So its 7x5 = $35
Answer $35
Answer:
D. Equally likely outcomes
E. Relative frequency
F. Cumulative frequency
Answer:
c > 9
Step-by-step explanation:
(2c/3) + 1 > 7 subtract 1 from both sides
2c/3 > 7 -1
2c/3 > 6 (multiply both sides by 3)
2c > 6(3)
2c>18 (divide both sides by 2)
c > 18 / 2
c > 9
Answer:
x^2 -81
Step-by-step explanation:
(x+9)(x-9)
FOIL
first x*x = x^2
outer -9x
inner 9x
last -9*9 = -81
Add them together
x^2 -9x+9x -81
Combine like terms
x^2 -81
