We know that :

⊕ Sum of the three angles in a triangle should be equal to 180°

Given : Angle BAC = 50° and Angle ABC = 75°

⇒ Angle BAC + Angle ABC + Angle ACB = 180°

⇒ 50° + 75° + Angle ACB = 180°

⇒ 125° + Angle ACB = 180°

⇒ Angle ACB = 180° - 125°

⇒ Angle ACB = 55°

Ashley had a summer lemonade stand where she sold small cups of lemonade for $1.25 and large cups for $2.50. if ashley sold a to

Levart [38]

The answer is 98 small and 57 large cups.

s - the number of small cups
l - the number of large cups

Ashley sold a total of 155 cups: s + l = 155
Ashley earnedfor $265: 1.25 * s + 2.50 * l = 265

s + l = 155
1.25 * s + 2.50 * l = 265
________
s = 155 - l
1.25 * s + 2.50 * l = 265
________
1.25 * (155 - l) + 2.50 * l = 265
193.75 - 1.25 * l + 2.50 * l = 265
193.75 + 1.25 * l = 265
1.25 * l = 265 - 193.75
1.25 * l = 71.25
l = 71.25 / 1.25
l = 57

______
s = 155 - l
l = 57

s = 155 - 57
s = 98

Solve for x. 144° 18 degrees 30 degrees 48 degrees 120 degrees

disa [49]

Answer:

Step-by-step explanation:

you have a rotation angle of 360 °, take out the known values (360 ° -90 ° -144 ° = 126), 144 ° is part of a flat angle of 180 °, from 180 ° remove 144 and you have 36 °, they are opposite angles therefore the same. therefore 360 - 144 - 90 - 36 - 36 = 54.

54 is 3x, so x = 18 ° (54 : 3 = 18)
