m∠3 = 70°
Solution:
Line l and line m are parallel.
line t and line s are transversals.
<em>Sum of the adjacent angles in a straight line = 180°</em>
50° + (x + 25)° + (2x)° = 180°
50° + x° + 25° + 2x° = 180°
75° + 3x° = 180°
Subtract 75° from both sides, we get
3x° = 105°
Divide by 3 on both sides of the equation.
x° = 35°
x = 35
(2x)° = (2 × 35)° = 70°
(2x)° and ∠3 are alternate interior angles.
<em>If two lines are parallel then alternate interior angles are congruent.</em>
m∠3 = (2x)°
m∠3 = 70°
Hence m∠3 = 70°.
Answer: 8.5 cups of flour.
Step-by-step explanation: So he first has 19/2 cups of flour, 19/2 cups of flour is the recipe, which is 9.5 cups of flour. He finishes the recipe with 17/2 cups left, which is 8.5 cups of flour.
Factor it out.
Both exponent cancel out each other which equals 1.
