Answer:

  x = 12.5

Step-by-step explanation:

The value of x is part of the value of an angle in a triangle where the other angles are known. This suggests that the relevant theorem is the "angle sum theorem," which tells you <em>the sum of angles in a triangle is 180°</em>.

This gives you the equation ...

  60° +60° +(4x+10°) = 180° . . . . total of all angles is 180°

  4x +130° = 180° . . . . . . . . . . collect terms

  4x = 50° . . . . . . . . . . . . subtract 130° from both sides

  x = 12.5° . . . . . . . . . divide both sides by 4

Please helppp will mark brainlyist with right answer

An angle bisector is a line or ray that divides an angle into two congruent angles
so
in this problem
m∠RST=m∠RSV+m∠VST
m∠RSV=m∠VST
hence
m∠RST=2*m∠RSV --------> equation 1
we have
m∠RST=(6x-24)
m∠RSV=(2x+8)
Substitute in the equation 1
6x-24=2*(2x+8)
6x-24=4x+16
6x-4x=16+24
2x=40
x=40/2
x=20 degrees
therefore
the value of x is 20 degrees

Need help ASAP!!! Tysm if you answer!! IF YOU ANSWER RIGHT AND GET BRAINLIEST!!
Delvig [45]

Answer:

a_n = 3 ({5})^{n - 1}

Step-by-step explanation:

The given sequence is 3,15,75,375,...

The first term of this geometric sequence is

a_1=3

The common ratio is

r =  \frac{15}{3}  = 5

The explicit formula is given by:

a_n = a_1 {r}^{n - 1}

We plug the first term and common ratio into the formula to get:

a_n = 3 ({5})^{n - 1}

Find the Sine of angle A<br> 8/17<br> 8/15<br> 15/8<br> 15/17
Vlad [161]

Given:

In triangle ABC, AB = 30, BC = 16, AC = 34 and measure of angle B is 90 degrees.

To find:

The value of Sine of angle A.

Solution:

In a right angle triangle,

\sin\theta=\dfrac{Perpendicular}{Hypotenuse}

In the given triangle ABC,

\sin A=\dfrac{BC}{AC}

\sin A=\dfrac{16}{34}

\sin A=\dfrac{8}{27}

Therefore, the correct option is A.
