Answer:
∠W = 16.3°
Step-by-step explanation:
In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
From that above question, we are given 3 sides and we are to find the angle of one of the sides.
We solve using Cosine rule.
∠W = arc cos (v² + x²﹣w²/2vx)
∠W = arc cos (64² + 63² - 18² /2 × 64 × 63)
∠W = arc cos (0.9599454365)
∠W = 16.27137°
∠W = 16.3°
Answer:
6 ---------> 2x : 48 = 3 : 12
9 ---------> 2 : 3 = 6 : x
16 --------> 12 : 15 = x : 20
24 -------> 4 : 7 = x : 42
Step-by-step explanation:
Answer:
t = 0.05 / 0.017
Step-by-step explanation:
Given the table :
Variable ____ Estimate
Intercept 1 ____ 15.5 ____2.96
Temp 1 _______0.05 ___ 0.017
R-sq = 0.73
The test statistic for a regression test :
t = b1 / E
Where ;
b1 = slope ; E = Standard error of the slope
From the result table ;
b1 = 0.05 ;
E = 0.017
The test statistic, t = 0.05 / 0.017
So hmmm notice the picture below
recall the "inscribed angle" theorem, an angle inscribed is half the intercepted arc
now, the line BA goes through the center, and to each end, thus is a diameter, the point of tangency, where a tangent hits the diameter or radius of a circle, is always a right-angle

yes
