Answer:
x = 4
Step-by-step explanation:
The quadrilateral is a rectangle and opposite sides are congruent, hence
10 + 2x = 18 ( subtract 10 from both sides )
2x = 8 ( divide both sides by 2 )
x = 4
=(3a-4a-3a)+(2b+6b-2b)+(-7c+9c-7c)
=-4a+6b-5c #
Since all triangles r equal to 180°
123+41= 164
180-164=16
the measure of the third angle of the triangle is 16°
Answer:
8
Step-by-step explanation:
times the 1/2 (2) by 4 because of half
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:

From here, we clear the value of x.
We have then:




Answer:
4/9 divided by 1/27 equals 12
