Answer:
I think It's option A
Step-by-step explanation:
But I am not sure It's correct or not
I hope It's helpful
The ratios of sides in a 30°-60°-90° triangle are such that the hypotenuse (AB) is double the length of the shortest side (AC). In your triangle, AC is the hypotenuse of similar triangle ACD, which has AD as its shortest side.
Then
(1/2)×(AD+54) = AC
(1/2)×AC = AD
Together, these tell you
AD = (1/4)(AD +54)
3×AD = 54
AD = 18
w = 55
y = 55
X = 125
z = 125
Step-by-step explanation:
Angles with in a cube add up to 360 degrees
Answer:
i believe it would be angle CDA or ADC (they are the same angle, just written differently)
Step-by-step explanation:
complamentary angles are angles that add up to be 90°.
Answer: 95.64% of the values will be below 212.5 in our set of data.
First, determine the z-score for the expected value of 212.5. The z-score is the number of standard deviations that it is above or below the mean.
(212.5 - 192.3) / 11.8 = 1.71
A score of 212.5 is 1.71 standard deviations above the mean. Now, use a table to find the probability for a z-score of 1.71. The percent is 95.64%.
