Answer:
Angle 1 = 119 degrees.
Step-by-step explanation:
3x + 31 = 6x + 1 (exterior alternate angles)
30 = 3x
x = 10
So the angle marked 6x + 1 = 6(10)+1
= 61
Angle 1 is adjacent to this so it is 180-61 = 119 degrees.
Answer:
Step-by-step explanation:
in general the parallelogram has same opposite angles.
or it has 68° and 112° as adjacent angles.
Answer:
<h3>x = -3 , x = 3</h3>
Step-by-step explanation:
7x² - 3 = 60
7x² - 3 - 60 = 0
7x² - 63 = 0
Simplify the terms
Divide both terms by 7
That's
x² - 9 = 0
Solve the quadratic equation
Use difference of two squares
That's
a² - b² = ( a + b)(a - b)
x² - 9 = 0
(x + 3)(x - 3) = 0
x + 3 = 0 x - 3 = 0
x = - 3 x = 3
