[1] First, remember that the sum of the angles in a triangle must add up to 180*.
[2] We are told two of the angles, 44* and 66*, but we are missing the third.
[3] Combining [1] and [2], we know that 44* + 66* + ? = 180*. In other words,
110* + ? = 180*
so,
? = 70*
The missing angle 3 is equal to 70 degrees.
Each of these equations follows the standard form: y = mx + b
The variable "m" is the slope, and the variable "b" is the y-intercept.
Therefore, with the equation y = 8/3x - 5, the slope ("m") would equal 8/3 and the y-intercept ("b") would equal -5
Answer:
y = 120º
Step-by-step explanation:
180 - (33 + 87) = 60
x = 60
180 - 60 = 120
y = 120º
or y = 33 + 87, because the outer angle of one angle equals the other two inner angles.
Answer:
X = -2
Step-by-step explanation:
1/2 X (5X-8) = -9
multiply both sides of the equation by 2
2 X 1/2 X (5X - 8) = 2 X (-9)
1 X (5X - 8) = 2 X (-9)
Reduce the numbers with the greatest common divisor 2
5 x -8 = 2 x (-9)
5 x -8 = -18
Move constant to the right by adding its opposite to both sides
5X -8 + 8=-18 + 8
Then eliminate the opposites
5X = -18 + 8
Calculate the sum
5X = -10
Divide both sides of the equation by 5
5X DIVIDE 5 = -10 DIVIDE BY 5
X = -10 DIVIDE BY 5
X = -2
