Answer:
MN = 3
Step-by-step explanation:
The following are congruent to each other as each pair are tangents of a circle drawn from the same external point:
PQ = QJ = 1
JK = KL = 4 - 1 = 3
MN = ML
Thus, ML = KM - KL
ML = 6 - 3 = 3
Therefore, MN = ML = 3 (both are tangents drawn from the same external point, M.
70+9x+7-21x-5=0
-12x=-72
x=6
Explanation:
The three inner angles of the triangle add up to 180. And if a straight line is split into two angles, those also add to 180 degrees. So we can make the equation '9x+7 + 70 + 180-(21x+5) = 180'
Answer:
1732.2097 has 8 significant figures.
Step-by-step explanation:
Every non-zero digit is considered a significant number. Also, in some exceptional cases, zero can also be considered a significant figure if it is in the middle of two non-zero digits.
Just like in the number given, 1732.2097. We have 7 non-zero digits which certainly would be considered to be significant figures. Zero is between two significant figures, 2 and 9, therefore, it would also be referred to as a significant figure.
Therefore, the number, 1732.2097, has 8 significant figures.
Answer:
Step-by-step explanation:
Assuming that arc AB is where the inscribed angle meets the outside of the circle, then the rule is that the inscribed angle is 1/2 of the measure of its intercepted arc. For us,
Solving for x:
2(5x - 7) = 2x so
10x - 14 = 2x and
8x = 14 so
x = 1.75
Answer:
75 cent.
Step-by-step explanation:
It's 51 + 24 because it grows one centimeter every month.
51 + 24 = 75 cent.
