Answer:
x + 90 = 120 degrees.
Step-by-step explanation:
4x = x + 90 (opposite angles are equal)
3x = 90
x = 30
So the 2 angles are
4 * 30 = 120.
x + 90 = 120
the marked angles are vertically opposite angles and are congruent , then
4x = x + 90 ( subtract x from both sides )
3x = 90 ( divide both sides by 3 )
then
x + 90 = 30 + 90 = 120
2.52 lbs=40.32 oz
I used the mass formula and I even searched it.
Hope this helps! :)
sorry I don't understand your question
According to above figure, the angles (8x - 20)° and (5x + 37)° are pairs of vertical opposite angles, so
