The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
x = 14.5
m∠DEA = 39.5°
m∠AEB = 140.5°
Solution:
Sum of the measures of adjacent angles in a straight line is 180°.
m∠DEA + m∠AEB = 180°
The numerical sum of the degree measures of ∠DEA and ∠AEB is 180°.
⇒ m∠DEA + m∠AEB = 180°
⇒ (x + 25)° + (9x + 10)° = 180°
⇒ x° + 25° + 9x° + 10° = 180°
⇒ 10x° + 35° = 180°
Subtract 35° from both sides of the equation.
⇒ 10x° = 145°
⇒ x° = 14.5°
⇒ x = 14.5
m∠DEA = (9x + 10)°
= (9(14.5) + 10)°
m∠DEA = 39.5°
m∠AEB = (x + 25)°
= (14.5 + 25)°
m∠AEB = 140.5°
Answer:
60
Step-by-step explanation:
The information's provided in the question is enough for reaching the desired solution of the question. No additional information is required at all. Only it is important to be careful about the calculation part as the multiplication is a little big.
49% of 1018 = (49/100) * 1018
= 49882/100
= 498.82
So the exact value of 49% of 1018 is 498.82. I hope there is no complexity in the above procedure and it is easy for you to understand. You can always use this method for solving any similar kind of problems in future without requiring any help from outside.
