What is the measure of triangle X in degree
Anna11 [10]

Answer:

A.) 40°

Step-by-step explanation:

A triangle is equal to 180°

Angle X and Y has the same angle, so both have 70°.

So:

70° × 2= 140°

To find the degree of the last angle, subtract the known degree, which is 140°, from the overall degree, which is 180°.

So:

180° - 140°= 40°

Answer= 40°

I hope this helps! :)

alexdok [17]

Answer:

Ameliorate retort, pertaining to preceding albeit contingent interrogate proximates subject to x = 12.

Step-by-step explanation:

Availing, exploiting, albeit maneuvering the Mathematic convention, Order of Operations (OO), the contiguous albeit proximate equation may ascertain as the preeminent imminent:

Groups: Not identified.

Exponents: Not identified, disparaging ₁.

Multiplication: Derived, pertaining to subtraction, 4 · (7/4x) = 4 · 21  <u>7x = 84</u>

Division: Derived, pertaining to multiplication, 7x = 84 ⇒ <em><u>x = 12</u></em>

Addition: Aggregate constants ⇒ 5/2x = 3/4x +21

Subtraction: Abate algebraic groups ⇒ 7/4x = 21

Read the information below and answer the questions. Suppose a researcher wants to learn more about the mean attention span of i
Anon25 [30]

Answer:

The population mean (μ) = 26.

Step-by-step explanation:

a) Data and Calculations:

The population characteristics = 20 and 36

Total population of interest = 56 (20 + 36)

Number of groups in the population = 2

Therefore, the population mean (μ) = 56/2 = 28

b) Based on the parameters given in this example, the population mean equals the average of the group characteristic (attention span of individuals in minutes) or item of interest.  The population mean is calculated by adding the values of the group characteristic and then dividing the result by the number of values.
