Answer: 116

Step-by-step explanation:

32 + 32 (because the angles are complementary) + 116 = 180!

Answer:

116 degrees

Step-by-step explanation:

well from the picture we know this is a 45 45 90 style triangle therefore in if CBE is equal to 32 then ECB should also be equal to 32 leaving you with a total number of 64 degrees within the triangle. and in every triangle you must add up the degrees to 180 so if we subtract 64 from 180 we get 116 degrees for BEC

Answer:

The another term for the 4% value is : Margin of error

Step-by-step explanation:

Dr. Cyril conducts a simple random sample of 500 men.

He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%.

Now, the another term for the 4% value is : Margin of error

Means the estimate of father being unsure about his ability would be between 19% and 27%.

When sample size is increased, the margin of error becomes smaller.

Find the measure of angleq, the smallest angle in a triangle whose sides have lengths 4, 5, and 6. round the measure to the near
Pavlova-9 [17]

The measure of the ∠Q = 41°

By law of cosines:

a law in trigonometry: the square of a side of a plane triangle equals the sum of the squares of the remaining sides minus twice the product of those sides and the cosine of the angle between them.

Which can we stated as:

{q}^2 = {p}^2 + {r}^2 - 2prcos(Q)\\{4}^2 = {6}^2 + {5}^2 - 2*6*5*cos(Q)\\\\

solving equation using normal algebra:

60cos(Q) = 36 + 25 - 16

60 cos(Q) = 45

cos(Q) = 45/60

cos(Q) = 3/4

Q = {cos}^{-1} (\frac{3}{4})\\

Thus, Q = 41°

Hence, the measure of the smallest angle in a triangle whose sides have lengths 4, 5, and 6. ∠Q is 41°.
