with a sum of 1809. If the measure of Angle o
is 33 more than six times the measure of Angle

Number 4
Answers
Answer:
∠C = 159°
∠D = 21°
Explanation:
∠C + ∠D = 180 (1)
∠C = 33 + 6∠D (2)
Substituting (2) to (1):
180 = 33 + 6∠D + ∠D
= 33 + 7∠D
180 - 33 = 7∠D
147 = 7∠D
21 = ∠D
If ∠D = 21,
∠C + 21 = 180
∠C = 180 - 21
∠C = 159

Set up the equation you would use to solve the problem.Do not actually solve the equation.
A plane flies 390 miles with the wind and 325 miles against the wind in the same length of time. If the speed of the wind is 10 miles per hour, fine the speed of the plane in still air. (Let x = speed of the plane.)
A. 390/x+20 = 395/x
B. 390/x+10 = 325/x-10
C. 390/x = 325/x-20
D. 390/x-10 = 325/x+10
Answers
Answer:
B is the answer because x- 10 = the speed of the plane going agianst the wind.
Explanation:
The equation to solve the problem is 390/x+10 = 325/x-10. Hence option B is correct.
What are equation?Equation is defined as a formula that demonstrates the equality of two mathematical expressions. Identify the question that is being asked. Write the pertinent details in straightforward statements. Give symbols for values that need to be discovered. Find the mathematical connections between the assertions. The equal to sign (=) is the best indicator of whether a given problem is an equation or an expression because it indicates that the problem is an equation.
If there are any brackets in the provided equation, remove them. The distributive property should be used. The same number should be added to both sides. Take from each side the same quantity. The same integer should be multiplied on both sides. Divide both sides by the same number.
Thus, the equation to solve the problem is 390/x+10 = 325/x-10. Hence option B is correct.
