In this parallelogram, angle A and B add up to 180 (they are supplementary). Set up an equation like this and solve:
3x + 4 + 143 = 180
3x + 147 = 180
3x = 33
x = 11
The measure of x is 11°.
I got -0.75. But is that a 3 and 1/2 or just 3?
Answer:
x = 0, x = - 3
Step-by-step explanation:
Given
5x² - 7x = 4x² - 10 ← subtract 4x² - 10x from both sides
x² + 3x = 0 ← in standard form
Factor out x from each term
x(x + 3) = 0
Equate each factor to zero and solve for x
x = 0
x + 3 = 0 ⇒ x = - 3
Start by adding 2 to both sides to get 3r^2 = 48. then divide both sides by 3 to get r^2 = 16. square root both sides to get r = 4.
