Hey I don't know who Mhanifa is but 25 is correct, and I will put the entire explanation to how to get the answer here.
First of all the 2 lines on the left and right side of the triangles are means that those 2 lines are equal and thus forming a isosceles triangle.
This means that the bottom right angle is also 2x+2 degrees.
Now because all 3 angles in a triangle adds to 180 degrees, we can set up equation.
3x+1+2x+2+2x+2=180
Now combine like terms
7x+5=180
Then solve, first subtract 5 from both sides.
7x=175
Now divide 7 from both sides
x=25
Compatible 50 x 120 = 6000
Rounding 50 x 123 =6150
Compatible numbers is closer estimate
It would be 220 rounded to the nearest ten because the number in the ones place does not equal or exceed 5.
So 220 is your answer :)
[(8+10)/3]+3.(7-3)=(18/3)+3.(4)=6+12=18
answer; <span>[(8+10)/3]+3.(7-3)=18</span>
The answer is -65.6 because the negative sign is on the out side of the absolute value signs.
