In ΔVWX, v = 64 cm, w = 18 cm and x=63 cm. Find the measure of ∠W to the nearest degree.
wariber [46]

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°

Nookie1986 [14]

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

I'm not sure how to set this up

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
