the inside of quadrilateral is always 360°.So add 75°,90° and 75° and then subyaract from360°.
x+75°+75°+90°=360
×+240°=360°
x=360°-240°
x=120°
A pair of perpendicular lines would be line CF and line AJ.
Line BC and line AJ are NOT perpendicular because when a pair of lines are perpendicular, all angles become 90 degrees. It is obvious, in the case, if you were to slide line BC on top of line AJ, the angles will not equal 90 degrees.
Answer:
The answer is A and B
Step-by-step explanation:
y-y=m(x-x)
y-(-3)=m(x-(-5))
y+3=0.4(x+5)
y-y=m(x-x)
y-1=0.4(x-5)
You would round 762 to 800, then you would round 332 to 300. You would take those 2 numbers and put them in the questions and it should look like this:
800-300, then you would subtract
Good luck!
From the figure. a and b are equal because the lines are parallel. The jargon is alternate interior angles are equal.
The two remote interior angles are equal to the exterior angle. That interprets to
b + 2a = 84o But b = a
a + 2a = 84o
3a = 84
a = 84/3
a = 28 <<<< answer
b = 28 <<<< answer
2a = 56 <<<< answer.
