Fine but I ain't showing my work completely.
The sum of all ext. angles of a polygon = 360.
So, you make this formula and solve for x.
360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27 /27
10 = x
Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57
Therefore, angle A is 57 degrees.
Answer:No
Step-by-step explanation:The side lengths do not make a right triangle, so it can't be tangent.
Hi there! I can help you! To find the unit rate, we divide fractions. Let’s divide by 2/3. To divide fractions, keep the first fraction the same, change division into multiplication, and flip the second fraction over. 1/4 * 3/2 is 3/8. There are 3/8 cup in 1 serving.
Answer:
362880 ways
Step-by-step explanation:
Given
10 digits
Required
Number of 10 digits that can be formed if no repetition and 2 must always start;
Since digit 2 must always start and no repetition is allowed, then there are 9 digits left
Digit 2 can only take 1 position
9 digits can be arranged without repetition in 9! ways;
Calculating 9!
Number of arrangement = 1 * 362880
Number of arrangement = 362880 ways
