In triangle $ABC$, the angles $\angle A$, $\angle B$, $\angle C$ form an arithmetic sequence. If $\angle A = 23^\circ$, then wha

LenKa [72]

Answer:

$97^0$

Step-by-step explanation:

Given that the angles A, B, C in a Triangle form an arithmetic sequence where A=23 degrees.

The nth term of an Arithmetic sequence is given by the formula: $T_n=a+(n-1)d$

Where:

a=first term

n=number of term

d=common difference

In this case,

$Angle \:A, a=23^0$

$Angle B, T_2=23+(2-1)d=(23+d)^0\\Angle C, T_3=23+(3-1)d=(23+2d)^0$

The sum of angles in a triangle is 180 degrees. Therefore:

∠A+∠B+∠C=180 degrees

$23^0+(23+d)^0+(23+2d)^0=180\\69^0+3d=180^0\\3d=180^0-69^0\\3d=111^0\\d=37^0$

Therefore:

Angle C,

$(23+2d)^0=(23+2(37))^0=23+74\\C=97^0$

The numbers a, b and c satisfy a+b+c = 0 and abc = 78. What is<br>the value of (a+b)(b+c)(c+a)?

djyliett [7]

Answer:

$(a+b)(b+c)(c+a)=-78$

Step-by-step explanation:

We are given that the numbers a, b and c

$a+b+c=0$ ....(1)

$abc=78$ ..... (2)

We have to find the value of (a+b)(b+c)(c+a).

From equation we get

$a+b=-c$

$b+c=-a$

$a+c=-b$

Substitute the values then we get

$(a+b)(b+c)(c+a)=(-c)(-a)(-b)$

$(a+b)(b+c)(c+a)=-abc$

Using equation (2) we get

$(a+b)(b+c)(c+a)=-78$

Hence, the value of $(a+b)(b+c)(c+a)$ is -78.
