Answer: 55
Step-by-step explanation: There is one simple theorem we need to know in order to solve for this.
Triangle Angle-Sum Property: All three angles interior angles of a triangle add up to 180°.
Thus, we could label the points A, B, and C, and set up an algebraic expression.
Let A = 27, B = 98, and C = x.
A + B + C = 180°.
Substituting A, B, and C we get:
27 + 98 + x = 180°.
Adding, we get:
125 + x = 180°
Subtracting 125 by 180, we get:
x = 55°
Thus, the angle X is 55°.
We could have simply solved this by just doing 180 - 98 - 27 = 55 in the first place, but I wanted to show you how I got such results.
Answer:
true for all x
Step-by-step explanation:
3(2x-4)=6(x-2)
Distribute
6x - 12 = 6x -12
Subtract 6x from each side
6x-12 -6x = 6x-12-6x
-12 =-12
Since this is always true, there are infinite solutions
7/8 x = 21
7x = 21×8
7x = 168
x = 24
A) 8 seconds hope this work :)
