Answer:
0.66(1.1 ^n -1)
Step-by-step explanation:
They are in GP!
S = (6.6)(1.1 ^n -1)÷(0.1)
Answer:
∠ 1 = 99°, ∠ 2 = 81°, ∠ 4 = 81°
Step-by-step explanation:
∠ 1 and ∠ 3 are vertical angles and are congruent, then
∠ 1 = 99°
∠ 1 and ∠ 2 are adjacent angles and sum to 180° , so
∠ 2 = 180° - 99° = 81°
∠ 2 and ∠ 4 are vertical angles and are congruent, so
∠ 4 = 81°
Step-by-step explanation:
3b - 3.76 = 1.34
3b = 3.76+ 1.34
3b = 5.1
b= 5.1/3
= 1.7
I believe question 3 is B and question 4 is B
I know the answers but I hate simplifying
