Answer:
Step-by-step explanation:
The identical arc symbols on the two angles indicates the angles are congruent. Also, these are alternate interior angles where a transversal crosses lines marked as parallel, so they are congruent:
∠A = ∠B
8x +78° = 2x +114° . . . . . substitute the given expressions
6x = 36° . . . . . . . . . . . . . subtract 2x+78° from both sides
x = 6° . . . . . . divide by 6
∠B = 2x +114° = 2·6° +114° . . . . . put the value of x into the expression
∠B = 126°
Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
If there are two cups in a pint, two pints in a quart, and four quarts in a gallon that means that there are 16 cups in a gallon. then, in order to convert, all you do is divide 152/16. when you divide this out, you get 9.5 gallons
