5/4 = 1.25
so
x + 1.25x = 180
2.25x = 180
x = 80
1.25x = 1.25(80) = 100
answer
angle and its supplement measure: 80 and 100
A square is a rectangle and a rhombus therefore the properties of parallelograms, rectangles, and rhombuses would all apply to a square. Meaning they must have parallel <span>sides as well as opposite angles that are </span>congruent <span>and consecutive angles that are supplementary.</span>
Answer:
C
Lucky guess if this is wrong i am truly sorry.
Step 1: Simplify both sides of the equation.
17−2n=9
17+−2n=9
−2n+17=9
Step 2: Subtract 17 from both sides.
−2n+17−17=9−17
−2n=−8
Step 3: Divide both sides by -2.
−2n−2=−8−2
n=4
