Step-by-step explanation:
sums of external angles of triangle =360°
360 - 130 -134
x = 96°
Answer:
The answer would be 1, whenever you square a negative number you should just input it as positive. The answer would be the same.
Step-by-step explanation:
Tan (0) is equal to 0
Sin (0) = 0
Cos (0) = 1
Tan = Sin/Cos
That means that Tan (0) = 0/1 or 0
2x + 1.5x +20 = 90
3.5 x = 90-20
3.5 x = 70
x = 70/3.5
x = 20
angle DAE = 2*20 = 40
angle CAD = 1.5*20 +20 = 50
