The pattern goes plus six, plus six, plus six. so the answer would be 19
Answer:
The measure of A is 93
Step-by-step explanation:
Here, we want to get the measure of angle A
we can start by getting the measure of angle C
Mathematically, we can use sine rule
It states that the ratio of the length of a side of a triangle and the sine of the angle it faces is constant
So to get C, we have the following;
9/sin 38 = 11/sin C
sin C = 11sin 38/9
sin C = 0.7525
C = sin^-1(0.7525)
C = 48.80
This is approximately 49
To get A,
we know that if we added the measure of interior angles of a triangle, the addition is 180 degrees
Thus, we have it that:
38 + 49 + A = 180
A = 180-38-49
A = 93

Step-by-step explanation:
<span>Muffins cost $1.25 and bagels cost $0.80.
We know by addition that 15 bagels and 12 muffins would cost $27. We can divide each term by 3 to simplify this and see that 5 bagels and 4 muffins would cost $9. Since we already knew that 5 bagels and 8 muffins cost $14, we can use subtraction to discover that 4 muffins cost $5. By dividing both sides of the equation by 4 we learn that a muffin costs $1.25. Once we know this we can plug this back into any equation to derive the cost of a bagel. For example 10b + (4 x 1.25) = 13, so 10b = 13 - (4 x 1.25), so, b = [13 - (4 x 1.25)]/10, so b = 0.80.</span>
