Find the value of the variables in each figure. Explain your reasoning.

sergiy2304 [10]

Answer:

see explanation

Step-by-step explanation:

The figure has one pair of parallel sides and is a trapezoid.

Each lower base angle is supplementary to the upper base angle on the same side, thus

15x + 30 + 10x = 180 , that is

25x + 30 = 180 ( subtract 30 from both sides )

25x = 150 ( divide both sides by 25 )

x = 6

Also

3y + 18 + 90 = 180 , that is

3y + 108 = 180 ( subtract 108 from both sides )

3y = 72 ( divide both sides by 3 )

y = 24

-------------------------------------------------------------------

2x, 90 and x lie on a straight line and sum to 180 , thus

2x + 90 + x = 180 , that is

3x + 90 = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

------------

2y and x are alternate angles and congruent , thus

2y = x = 30 ( divide both sides by 2 )

y = 15

I need Geometry help!!!!

Goryan [66]

What we know:
1. y = 2x because angles facing each other are equal to each other
2. A straight line means 180 degrees.

Steps:
y + (x + y + 5) = 180
2y + x = 175
2 (2x) + x = 175
5x = 175
x = 35
y = 2 (35) = 70

Brad wants to open a new savings account. He finds one that returns 3% on his investment each year. Use the variable to write a

Jet001 [13]

Return rate, r = 3% = 0.03
x = initial investment
b = final balance

After 1 year, the balance i
b = initial investment + interest
b = x + r*x = (1 + r)*x

Because r = 0.03,
b = 1.03x (after 1 year)
