Answer:
44
Step-by-step explanation:
The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.
The base angles are equal and found as follows.
2*b + 92 = 180 Subtract 92 from both sides
2b +92-92 = 180-92
2b = 88 divide by 2
2b/2=88/2
b = 44
The only angle measurement that fits is 44

Answer:
1 3/4 cups
Step-by-step explanation
Since the recipe calls for 5 1/2 cups of flower and Molly only has 3 3/4 cups, subtract 3 3/4 from 5 1/2 to get the remaining cups of flour needed to make the recipe.
5 1/2 - 3 3/4 = 1 3/4
Answer:
17,37
Step-by-step explanation:
one number = x
The positive number = 2x + 3
x * (2x+3) = 629
x*2x + x *3 = 629
2x² + 3x - 629 = 0
2x² - 34x + 37x - 17*37 =0
2x*(x -17) + 37(x - 17) = 0
(x - 17)(2x + 37) = 0
x - 17 = 0 ; Ignore 2x + 37 as s is a positive number
x = 17
Positive number = 2*17 +3 = 34+3 = 37
