Answer:
88°
Step-by-step explanation:
5a + 18 + 24 - a + 8a - 30 = 180 (angles on a straight line)
=> 12a + 12 = 180
=> 12a = 168
=> a = 168 / 12
=> a = 14
5a + 18 = 5 (14) + 18 = 70 + 18 = 88
24 - a = 24 - 14 = 10
8a - 30 = 8 (14) - 30 = 112 - 30 = 82
Therefore, largest angle is 88°.

Find the value of X and Y
Answer:
x = 30
y = 5
Step-by-step explanation:
Because the top triangle shows 3 congruent angles, we know it's an equilateral.
Therefore 8y = 40
y = 5
______________
Now we have two sides of the triangle: 40 and 80.
The lower left angle of the whole triangle must be 90 degrees because if the hypotenuse is twice the adjacent side, it must be a 30-60-90 triangle.
So, the larger angle containing angle x must be 90 degrees. And because we know that the adjacent angle (equilateral triangle) is 60 degrees, angle x must be 30.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) − 210°. Find m∠Y.
Answer:
m∠Y = 50°
Step-by-step explanation:
let 'm' = m∠Y
m∠S + m∠Y = 90 (complementary)
5m - 210 + m = 90
6m = 300
m = 50

Step-by-step explanation:
the ratio of two sums of money are 4:5. the first sum is $6. what is the second?
The second sum of money is $7.5
The ratio of the sum is given as:
Ratio = 4 : 5
Represent the second sum of money with x.
So, we have:
4 : 5 = 6 : x
Express the ratio as a fraction
4/5 = 6/x
Make x the subject of formula
x = 6 * 5/4
Evaluate the product
x = 7.5
Hence, the second sum of money is $7.5

Explain why parallel lines have different y intercepts
Answer:
The lines are parallel. The slopes of the lines are the same and they have different y-intercepts, so they are not the same line and they are parallel. Two non-vertical lines are perpendicular if the slope of one is the negative reciprocal of the slope of the other.
Step-by-step explanation:
Answer:
Because Y- intercept mean the part that a graph cuts at Y - axis
Step-by-step explanation:
If parallel lines cut at the same pint then they will not be parallel
