Answer:

60°

Step-by-step explanation:

Since, x and 2x are supplementary angles.

\therefore \: x + 2x = 180 \degree \\  \\  \therefore \: 3x = 180 \degree \\  \\ \therefore \: x =  \frac{180 \degree}{3}  \\  \\  \huge \red{ \boxed{\therefore \: x = 60 \degree}}

A man walks 4km from point x due east of point Y. The bearing of a flag point x and y are due N80°W and N40°E respectively. Find
In-s [12.5K]

The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Sine rule shows the relationship between the sides and angles of a triangle.

The triangle formed has angles A = 10°, B = 50°, C = 120°, c = 4 km, a = distance from point y.

Hence:

a / sinA = c / sinC

a / sin(10) = 4 / sin(120)

a = 0.8 km

The distance of the flag pole from point Y is 0.8 km and it is placed at an bearing of N40°E

SOMEONE HELP ME WITH MATH PLEASE !
Alla [95]

Answer:

C

Step-by-step explanation:

First, eliminate choice B b/c the max is 28, not 26.

Next, lets find the median.

(12+18+20+20+24+26+28+28) = (20+24)/2 = 22

That leaves us with only A & C as a possible answer.

Q1 = The median of the first half of the data (12, 18, 20, 20)

Q1 = (18+20) / 2 = 19

A & C have the same Q1 values, so we need to compare Q3 values.

Q3 = The median of the second half of the data (24, 26, 28, 28)

Q3 = (26+28) / 2 = 27

The Correct Answer is C b/c A had a different Q3 value.
