what
Step-by-step explanation:
Answer:
93°
Step-by-step explanation:
By exterior angle theorem:
(4x + 9)° = 2x° + (3x - 12)°
(4x + 9)° = (2x + 3x - 12)°
(4x + 9)° = (5x - 12)°
4x + 9 = 5x - 12
4x - 5x = - 12 - 9
-x = - 21
x = 21
Measure of exterior angle
= (4x + 9)°
= (4*21 + 9)°
= (84 + 9)°
= 93°
0.004 is read as four-thousandths, so write it as fraction using a 4 in the numerator and a 1000 in the denominator. Then reduce it.
0.004 = 4/1000 = 1/250
0.004 hours = 1/250 hours
