Answer:
the second store has the better deal.
Step-by-step explanation:
12 ÷ 2 = 6
7.5 × 6 = 45
20.2 < 45
Supplementary angles need to equal 180 degrees
one angle = t
the other angle = 4 x t or 4t
so we now have t + 4t = 180
4 + 4t = 5t
so we have 5t = 180
divide both sides by 5:
t = 180 /5
t = 36
so angle t = 36 degrees
the other angle = 4 x 36 = 144 degrees
Answer: 15
Explanation:
Let’s assume A = 5x -24 and B = 8x+9. Also, let’s assume the angle right beside B = C just so it doesn’t get confusing.
The two triangles are congruent so all the angle of the vertices for the smaller triangle align with the angle of the vertices for the bigger triangle. Since the triangles are the congruent, we can assume that Angle A also applies to angle C. So far, C = 5x -24. If you look carefully, C and B form a straight line (180 degrees).
180 = C + B
180 = (8x+9) + (5x-24)
180 = 13x- 15
13x = 195
x = 15
Answer:
<A=35
Step-by-step explanation:
70+x+79+x+39=180
2x+188=180
2x=-8
x=-8/2 or -4
<A=x+39
<A=-4+39
<A=35
