tan(angle) = opposite/adjacent

tan(B) = AC/AB

tan(B) = 9/7

B = arctan(9/7)

B = 52.125 which is approximate

B = 52

--------------------------------------

The final answer is choice D) 52 degrees

the answer is 52°

use the laws of trig

its a right triangle, so cotan 9/7 is 52°

ABC is isosceles.<br>m &lt; a = 3x + 40 and m &lt; c = x + 50<br>what is m &lt; a ??​
il63 [147K]

Answer:

  • 55°

Step-by-step explanation:

<u>It is assumed the angles A and C are congruent:</u>

  • 3x + 40 = x + 50
  • 3x - x = 50 - 40
  • 2x = 10
  • x = 5

m∠A = 3*5 + 40 = 55°

Use the given confidence interval limits to find the point estimate p^ and the margin of error E. 0.325
diamong [38]

Answer:

0.350

Step-by-step explanation:

Confidence interval = point estimate ± margin of error

Point estimate = Confidence interval - margin of error

To get the margin of error, we will take the average of the difference of the interval given. Given the confidence interval 0.325<p<0.375

Margin of error = 0.375-0.325/2

Margin of error = 0.050/2

Margin of error = 0.025

Using the interval of 0.375

Point estimate = 0.375 - 0.025

Point estimate = 0.350
