For a cyclic quadrilateral
The opposite angles are supplementary (meaning they sum up to 180 °)
I.e (x +20) ° + 3x ° =180 °
20 + 4x = 180
4x=180 - 20
4x = 160
Divide through by 4
x = 40 °
Angle at point A
(2x + 38) = (2(40) + 38) = 118 °
Angle at point B
3x = 3(40) = 120 °
Angle at point D
x + 20 = 40 + 20 = 60 °
Angle at point C
The total angle in a quadrilateral is 360 °
I.e 118 + 120 + 298 +
Answer:
yes because it does not have a exponent
Step-by-step explanation:
Answer:
Each term is separated by an addition or subtraction sign.
Coefficients are numbers in front of a variable (letter).
Constants are numbers with nothing else.
so you get
2 | 2 | 3 | 1
6 | 6 | 0.2, -1, 8 | 1/2
3 | -3 | - | -
