The two lines are perpendicular because both of the lines intersects
The ' c ' in 'gcf' and in 'lcm' stands for 'common'. 'Common' means 'same for all of them'. There's nothing common until you have at least two things. There's no such thing as the gcf or the lcm of only one number.
Answer:
Step-by-step explanation
larger angle = 76+2x
smaller angle = x
supplementary angles add up to 180
∴(76+2x)+x=180
76+3x=180
3x= 180-76
3x = 104
x = 104/3
x = 34.7°(smaller angle)≈ 35
larger angle = 76+2(34.7)
=76+69.4
=145.4≈ 145
The answer is D. Most students are young enough not to have much of a credit score or credit history...
From the diagram, 6y = 90 [right angle]
y = 90/6 = 15
Also, 5y + 3x + 6y + 90 = 360 [sum of interior angle of a quadrilateral is 360]
5(15) + 3x + 6(15) + 90 = 360
75 + 3x + 90 + 90 = 360
3x = 360 - 255 = 105
x = 105/3 = 35
Therefore, x + y = 35 + 15 = 50.
