Answer:
x = 4, ∠I = 33°
Step-by-step explanation:
<u>Question 1</u>
Converse to Base Angles Theorem: 28 = 9x - 8,
28 = 9x - 8 (add 8 to both sides)
9x = 36 (divide both sides by 9)
x = 4
<u>Question 2</u>
Since the triangles are congruent, ∠A ≅ ∠G:
∠A = 55 = ∠G
If we consider triangle ALX we have ∠L = 180-55-92 = 33°
And since ∠L ≅ ∠I, ∠I = 33° respectively
Answer:
$14400
Step-by-step explanation:
Given data
Principal= 6000
Time= 14 years
Rate= 10%
Let us use the simple interest expression to find the final amount
A=P(1+rt)
substitute
A=6000(1+0.1*14)
A=6000(1+1.4)
A=6000*2.4
A=$14400
Hence based on a simple interest model the final amount is $14400
Answer:
15+6x=75
Step-by-step explanation:
15 is the starting fee and it is 6$ per class so it would be 6x+15=75
Answer:
