I gotchu I’ll reply in like 2 mins in the comments chill and just know that I feel the pain of a timed assignment;)
A+c = 150
10.25a+7.75c = 1470
m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°
<h3>How to determine the angles</h3>
It is important to note that the sum of angles in a triangle equals 180°
The given structure is a triangle, thus, the angles sum up to 180°
m ∠ A + m ∠ B + m ∠ C = 180°
m∠ A = 60°
m ∠ B = 60°
m ∠ C = 60°
The sum of the angle in the triangle = 60° + 60° + 60° = 180°
Thus, m∠ A = 60°, m∠ A = 60°, m∠ A = 60° and the sum of the angles in the triangle is 180°

Which is not a geometric progression 4,8,16,32. 3,6,9,12. 2,618,54. 1,5,12,125

Answer:
see explanation
Step-by-step explanation:
A geometric progression has a common ratio r between consecutive terms
That is each term in the sequence is obtained by multiplying the previous term by r
Consider 4, 8, 16, 32
4 × 2 = 8
8 × 2 = 16
16 × 2 = 32
This is a geometric progression with r = 2
Consider 3, 6, 9, 12
3 × 2 = 6
6 × 2 = 12 ≠ 9
This is not a geometric progression
Consider 2, 6, 18, 54
2 × 3 = 6
6 × 3 = 18
18 × 3 = 54
This is a geometric progression with r = 3
Consider 1, 5, 12, 125
1 × 5 = 5
5 × 5 = 25 ≠ 12
This is not a geometric progression
Answer:b=-10.5, a=31.5
Step-by-step explanation: 3b=-a , -3b=a
a+b =21
-3b+b = 21
-2b=21
b=-10.5
a=-3b
a=-3*-10.5=31.5
