Answer:

The given measurement will produce only 1 triangle

Step-by-step explanation:

Given:

a = 13

c = 15

∠A = 53°

now, applying the law of sine, we have

(a/sinA) = (c/sinC)

on substituting the values, we get

(13/sin53°) = (15/sinC)

or

sinC = 0.921

or

C = 67.14°

also, sum of all the angles of a triangle = 180°

thus,

∠A + ∠B + ∠C = 180°

53° + 67.14° + ∠B = 180°

or

∠B = 59.85°

now,

again applying the law of sine, we have

(a/sinA) = (b/sinB)

on substituting the values, we have

(13/sin53) = (b/sin59.85°)

or

b = 14.07

now, we have all the dimension of the triangle and have obtained the unique values,

Therefore, the given measurement will produce only 1 triangle

Determine if the sequence below is arithmetic or geometric and determine the
Paladinen [302]

Answer:

Arithmetic sequence

Step-by-step explanation:

A sequence is described as an arithmetic sequence when there is a common difference between the numbers

A sequence is a geometric sequence when there is a common ratio between the numbers

12,10,8

10-12= -2

8-10= -2

10/12= 0.83

8/10= 0.8

Hence the sequence is an arithmetic sequence with a common difference of -2
