That triangle is isosceles, so the bottom two angles will always be equal. With that said, the equation will be 2(65), and that equals 130. After that, subtract 180-130, and that gives you x! In total, your calculations should look like this:
2(65)
180-130
x=50°
Answer:
Step-by-step explanation:
Given that a coin is flipped 5 times. Let us assume it is a fair coin with probability for head or tail equally likely and hence 0.50
Sample space would have 
possibilities
For two heads never occurring in a row favourable outcomes are
HTTTT,HTTHT,HTTTH, HTHTH, HTHTT, THTHT, THTTT, THTTH, TTHTH, TTHTT, TTTHT, TTTTH, TTTTT, TTTTH
Hence probability =
Favorable outcomes/Total outcomes=
Answer:
129 degrees
Step-by-step explanation:
The sum of all the angle of a quadrilateral is always 360 degrees, 51+90+90+129=360
The USA has 250,000 rivers
Answer: 12 servings
Step-by-step explanation:
If the lunch lady makes equal servings of 1/2 pound each and she had 6 pounds total it would be written like this: 6÷1/2
but you can't divide by a fraction so you multiply by the opposite reciprocal like this 6×2/1 or just 6×2
which gives you your answer of 12
