Answer:

\huge\boxed{x=29;\ y=51}

Step-by-step explanation:

This is Isosceles triangle (look at the picture).

We know:

All triangles have internal angles that add up to 180°

Therefore:

(x-2)+(x-2)+(4x+10)=180

combine like terms:

(x+x+4x)+(-2-2+10)=180\\\\6x+6=180\qquad|\text{subtract 6 from both sides}\\\\6x=174\qquad|\text{divide both sides by 6}\\\\x=29

(x - 2)° and 3y° are supplementary angle (Two Angles are Supplementary when they add up to 180°).

Therefore:

3y+(x-2)=180

substitute x = 29 and solve for y:

3y+(29-2)=180\\\\3y+27=180\qquad|\text{subtract 27 from both sides}\\\\3y=153\qquad|\text{divide both sides by 3}\\\\y=51

Look carefully at the triangle solve for x ​
luda_lava [24]

The 3 inside angles of a triangle need to equal 180 degrees. Looking at the larger outside triangle the top angle is 30 and the lower right angle is 60.

30 + 60 = 90

The lower left angle needs to be 180 - 90 = 90 degrees.

That angle is split into two angles with one given as 70.

This means X needs to be 90 - 70 = 20 degrees.

x = 20

Given 6x + b/c = a, rearrange the equation for b, in terms of a, c, and x.
SVEN [57.7K]

Answer:

b = c(a - 6x )

Step-by-step explanation:

Given

6x + \frac{b}{c} = a ( subtract 6x from both sides )

\frac{b}{c} = a - 6x ( multiply both sides by c to clear the fraction )

b = c(a - 6x)

kondaur [170]

Answer:

Button #4. The last button. 8p = t.

Step-by-step explanation:

This is because there are 8 pieces of string, and p is equal to the length of one string, so one string times 8 is the total length of all the strings.
