A, B, C, D form a complete circle which is 360 degrees.
Add all 4 together:
A + 2A + 4A+ 3A = 360
10A = 360
Divide both sides by 10:
A = 360/10 = 36
Now we know A so can calculate the rest:
B = 2A = 2(36) = 72 degrees
C = 4A = 4(36) = 144 degrees
D = 3A = 3(36) = 108 degrees
Answer:
x = 38°
Step-by-step explanation:
Complementary angles = 90°
90° = x + x+14
90° = 2x + 14
104 = 2x
x = 52°
the next angle should be 52 - 14 = 38°
So x = 38°

Answer:
double plus two , two apart facts make ten extended strategy is used.
Step-by-step explanation:
Sum of 5 + 7 = 12 less two = 12; OR to make 10, I need to take 3 from the 5, add it to the 7 to make 10 and that leaves 2 from the 5. I add the 2 to the 10 I now have and that = 12.
To find X, set up a ratio with the given dimensions:
10/15 = X/42
Cross multiply:
420 = 15x
Divide both sides by 15:
x = 420 / 15
x = 28
