Answer:
i don't know how to do it
You divide 5 and 16 to get the answer: 0.3125.
11a = 18a + 21
11a - 18a = - 18a + 21
-7a = 21
7a = -21
a = -21/ 7
a = -3
Answer:
61
Step-by-step explanation:
Because all triangles's angles sum is always equal to 180, we can establish the equation, (9x - 31) + (7x - 2) + (4x + 33) = 180.
Simplifying, we get;
9x - 31 + 7x - 2 + 4x + 33 = 180
20x = 180
x = 9.
So, angle DCE = 7x - 2 = 7 * 9 - 2 = 63 - 2 = 61
