Answer:
The value of x is 26.
Step-by-step explanation:
In a triangle, the total angles is 180°. In order to find the value of x, you have to add up all the angles in terms of x and make it equals to 180°
2x + 3x + 50 = 180
5x + 50 = 180
5x = 180 - 50
5x = 130
x = 130 ÷ 5
x = 26
10(4x+3)-9x
40x+30-9x
31x+30
I think the answer is A
D. centimeters (cm)
km is too large of a unit for this measurement, kg is a unit of weight not distance, mm is small but you'd rather choose cm
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line...:)
