Answer:

x = 17

Step-by-step explanation:

These angles are supplementary so (2x + 5) + (8x = 5) = 180 then you just do the algebra

Which of the sequences is an arithmetic sequence?

boyakko [2]

The sequence which shows arithmetic sequence is -3, -10, -17, -24, -31, ....... so the correct option is Option D.

<h3>What is Arithmetic Sequence?</h3>

An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.

Here, out of the given option option D follows the definition.

Difference between two consecutive term is equal.

-10 - (-3) = -10 + 3 = -7

-17 - (-10) = -17 + 10 = -7

-24 - (-17) = -24 + 17 = -7

-31 - (-24) = -31 + 24 = -7

Thus, the sequence which shows arithmetic sequence is -3, -10, -17, -24, -31, ....... so the correct option is Option D.

The m<6 = (11х + 8)° and m<7 = (12x – 4)°<br> What is the measure of <4

Travka [436]

Answer: m<4 = 40

Explanation: m< 6 = m< 7 (vertical angles)

11x + 8 = 12x – 4

12x - 11x = 8 + 4

x = 12

m< 6 = 11x + 8

m< 6 = 11(12) + 8

m< 6 = 132 + 8

m< 6 = 140

m<4 = 180 - m<6

m<4 = 180 - 140

m<4 = 40

answer

m<4 = 40

Use the law of sines to solve the given problem. A small island is approximately a triangle in shape. If the longest side of the

shutvik [7]

Answer: the shortest side is 279.24 feet

Step-by-step explanation:

The diagram of the triangle in shown in the attached picture. The given angles of 30 degrees and 50 degrees are for the shorter sides.

Since the sum of angles in a triangle is 180 degrees, it means that the angle of the longer side, x will be

x = 180 - (30 + 50)

x = 180 - 80 = 100 degrees

The sine rule states that

a/sinA = b/sinB = c/sinC

c = 550

a = the shortest side.

Therefore

a/sinA = c/ sinC

a/sin30/= 550/sin100

asin100 = 550sin30

0.9848a = 550×0.5 = 275

a = 275/0.9848

a = 279.24 feet
