-9 to the second power will most likely be 81. A negative x a negative equals a positive. Hope this helped.
Answer:
Part A
This equation is given as
180° = ∠A + ∠B
180° = (2x+5)° + (4x+25)°
Part B
The value of x = 25°
Step-by-step explanation:
We are told in the question that:
Angles A and B are adjacent angles and are supplementary. The measure of ∠A is (2x+5)∘ and the measure of ∠B is (4x+25)∘.
Question 1 Part A Write an equation that can be used to determine the value of x.
Two angles are called supplementary when their measures add up to 180 degrees.
This equation is given as
180° = ∠A + ∠B
180° = (2x+5)° + (4x+25)°
Part B
Solving the equation
180° = (2x+5)° + (4x+25)°
180° = 2x + 5 + 4x + 25
180° = 6x + 30
Collect like terms
180° - 30° = 6x
150° = 6x
x = 150/6
x = 25°
Enter the correct answer in the box.
The answer is 2/3 because 3/8x16/9= 2/3
