Answer:
x = 35° , y = 90°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
145° is an exterior angle of the triangle , then
y + 55° = 145° ( subtract 55° from both sides )
y = 90°
the sum of the 3 angles in a triangle = 180° , then
x + y + 55° = 180°
x + 90° + 55° = 180°
x + 145° = 180° ( subtract 145° from both sides )
x = 35°
She can wear outfits differently in 167 days.
Given that Lucy wants to wear different clothes everyday, and she has 8 dresses, 7 pairs of shoes, and 3 pairs of earrings, and Lucy can choose 1 dress, 1 pair of shoes, and 1 pair of earrings every day, but however 1 dress and 1 pair of shoes don't look good together, to determine, in such circumstances, how many days can she wear outfits differently, the following calculation must be made:
- (8 x 7 x 3) - 1 = X
- 168 - 1 = X
- 167 = X
Therefore, she can wear outfits differently in 167 days.
