9514 1404 393

Answer:

  • (2x-10) +x +(x+10) = 180
  • x = 45
  • (2x-10)° = 80°
  • (x+10)° = 55°
  • x° = 45°

Step-by-step explanation:

The equation is an expression of the fact that <em>the sum of the angles in a triangle is 180°.</em>

  (2x -10)° +x° +(x +10)° = 180°

For the purposes of the answer box, I'd leave off the degree symbol:

  (2x -10) +x +(x +10) = 180

__

This simplifies to ...

  4x = 180

  x = 45

Then the angles (CW from top) are ...

  (2·45 -10) = 80°

  (45 +10)° = 55°

  (45)° = 45°

Question 9<br> The triangles shown are
yaroslaw [1]

Answer:

The triangles shown are<u> proportional</u>

Step-by-step explanation:

Two parallel lines are cut by a tranversal so the opposite and corresponding angles are congruent.

B = N

M = M

12 x 2 = 24 , So the sides of the triangle are proportional meaning they are parallel.

Side MN would be 12

Side MP would be 16

Can you slove this 6=2(y+2)
Lisa [10]

Answer:

y=1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6=2(y+2)

6=(2)(y)+(2)(2)(Distribute)

6=2y+4

Step 2: Flip the equation.

2y+4=6

Step 3: Subtract 4 from both sides.

2y+4−4=6−4

2y=2

Step 4: Divide both sides by 2.

2y/2  2/2

What is the volume of a cone with a radius of 2 and a height of 19?
kykrilka [37]

Remember that the cone volume formula is V=\pi r^2\frac{h}{3} , with r = radius and h = height. Using our information, we can form our equation as such: V=\pi 2^2\frac{19}{3} (I'll be keeping the answer in pi form.)

Firstly, solve the exponents:V=\pi 4\frac{19}{3}

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3

For a ride on a rental scooter, John paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for
enot [183]

The linear equation is 8+0.06x=19.94 and John rode the scooter for 199 minutes.

Fee to start the scooter = $8.

Fee to ride per minute = 6 cents = $0.06.

Total bill = $19.94.

Let x be the minutes for which he rides the scooter.

The linear equation is formed as:

8+0.06x=19.94

0.06x=19.94-8

0.06x=11.94

x=199 minutes.

So, John rode the scooter for 199 minutes.
