x^+9x+20=0
Answer:
Step-by-step explanation:
• The measure of angle B is 70°
• The measure of angle Cis (4x)
What is the value of x?
The measure of the value x of the triangle is x = 20.
Given data:
In a triangle, the sum of the angles is always 180 degrees. Therefore, we can set up an equation using the given angle measures:
Angle A + Angle B + Angle C = 180
Substitute the given angle measures:
(2x - 10) + 70 + 4x = 180
Combine like terms:
6x - 10 + 70 = 180
Simplify:
6x + 60 = 180
Now, subtract 60 from both sides of the equation:
6x = 120
Finally, divide both sides by 6 to solve for x:
x = 20
Hence, the value of x is 20 and the angles are solved.

x is equal to 20.
The angles of one triangle always add up to 180°, so we can add the measures of each angle together and make an equation.
equation —> 2x - 10 + 70 + 4x = 180
After combining like terms, we get 6x + 60 = 180.
Then we can subtract 60 from both sides to isolate the variable, and the equation becomes 6x = 120. Then we can divide both sides by 6 to get the value of x. The equation becomes x = 20.
To find the circumference of a circle, you can use the formula C=2πr, where C is the circumference, π is a constant that is approximately equal to 3.14, and r is the radius. Plugging in the given value of r=6 yards, we get:
C=2×3.14×6
C=37.68
Rounding to the nearest hundredth, the circumference is 37.68 yards.
