Find the value of x in the triangle shown below

Mathematics
2 answers:
konstantin123 [22]2 years ago

Answer:

x = 55

Step-by-step explanation:

Since 2 sides of the triangle are congruent, both 5, then the triangle is isosceles and the 2 base angles are congruent, both x , then

x + x + 70 = 180 ← sum of 3 angles = 180°

2x + 70 = 180 ( subtract 70 from both sides )

2x = 110 ( divide both sides by 2 )

x = 55

Answer:

55.52

Step-by-step explanation:

By sine rule:

\frac{ \sin x \degree}{5}  =  \frac{ \sin 70 \degree}{5.7} \\  \\  \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\  \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\  \\ x \degree =  {sin}^{ - 1} ( \frac{ 5 \: \sin 70 \degree}{5.7}) \\  \\ x \degree = 55.516753493 \degree\\  \\ x = 55.52

Help me please i need the correct answer
BaLLatris [955]

Answer:

First one is 25/2

Step-by-step explanation:

12×2+1=25/2

9×4+1=36/4

cross multiply and you get

100/

divide both by 2 and you get 50/4 then you divide both by 2 again and you get 25/2 because you can't reduce it anymore

What is the value of tan x°?
dmitriy555 [2]
Hi there!

\tan(x)  =  \frac{opposite \: side}{adjecent \: side}
\tan(x)  =  \frac{8}{6}
\tan(x)  = 1 \frac{1}{3}

x = 53.1
Therefore tan x° = 1 1/3 and x = 53.1°

PLS HELP!! AND HURRY!! Find an expression for the nth term ( tn ) in each of the following sequences:
fiasKO [112]

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

From this definition, we can write a_n in terms of a_1:

a_2=a_1+3

a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3

a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3

a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3

and so on, up to

a_n=a_1+(n-1)\cdot3

(notice how the subscript on <em>a</em> and coefficient on 3 add up to <em>n</em>)

or

a_n=1+3(n-1)=3n-2
