Question 14 (Fill-In-The-Blank Worth 4 points) (05.02 MC) Find the measure of angle x. Round your answer to the nearest hundredt
patriot [66]

Answer:

22.62°

Step-by-step explanation:

Looking at the attached diagram, it is a right angled triangle. If we are to solve for the measure of angle x , we would be using the Trigonometric function of cosine

The formula is given as

cos x = Adjacent/ Hypothenuse

Adjacent = 12

Hypothenuse = 13

Therefore,

cos x° = 12/13

x° = cos -¹ (12/13) or arccos (12/13)

x° = 22.619864948°

Therefore, the measure of x to the nearest hundredth = 22.62°

Find the 9th term in the following geometric sequence.. round your answer to the nearest tenths.. 5,8.5,14.45,24.565.
fredd [130]
The geometric sequence:
a 1 = 5, a 2 = 8.5,  a 3 = 14.45,  a 4 = 24.565,...
r = 8.5 / 5 = 1.7
a n = a 1 * r^(n-1)
a 9 = 5 * 1.7^(8) = 5 * 69.757574
a 9 = 348.7878205 ≈ 348.8
