I need help finding y
Answer:
y = 9.8995
Step-by-step explanation:
This question requires the use of basic trigonometry.
In this problem, we know one of the sides and two of the angles.
Since one of the angles is 45 degrees and the sum of all internal angles of a triangle is 180 degrees, the other angle can only be 45 degrees, making this an isosceles triangle - that is, the length of the other leg, x, is also 7.
You could use the soh cah toa mnemonic to figure it out, but here just using the a^2 + b^2 = c^2 should be sufficient since we know both legs of the triangle.
7^2 + 7^2 = 98, and the square root of 98 gives you about 9.8995, which sounds about right for this situation.
Hope this helped!
Use the distributive property to write an expression that is equivalent to 1/2 (8y + (-x) + 12)
Algebra
[tex] \frac{1}{2} (8y - x + 12) = a[/tex]
Divide everything by two, or times everything by 1/2.
[tex]4y - \frac{1}{2} x + 6 = a[/tex]
This is as far as you could go due to no like-terms.

What is the slope of the line with the equation y +2 = -3(x – 7)?
OA.m = -3
O B. m = 3
O C. m = 2
O D. m = -7
Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)

Nuts Berry Farm sells nuts for $60 for 4 pounds. Today, and just for today only,
Nuts Berry Farm is giving a 30% discount to all those who will buy nuts today.
Enter how much, in dollars, is a pound of nuts today after the discount.
Answer:
$10.50
Step-by-step explanation:
First, find the cost of a pound of nuts.
Divide the price by the number of pounds:
60/4
= 15
Calculate the price with the 30% discount by multiplying this by 0.7:
15(0.7)
= 10.5
So, after the discount, a pound of nuts will cost $10.50

If the two triangles are similar, then their sides are proportional.
EC we know immediately. If the whole side BC = 12 = BE + EC, and BE is 4, then EC = 8.
Therefore, I can say that BD / (BD + DA) = BE / (BE + EC). To solve the problem for side DA, x will be used in place of DA.
8 / (8 + x) = 4 / (4 + 8)
8 / (8 + x) = 4 / 12 || Cross-multiply
4(8 + x) = 12 * 8
32 + 4x = 96
4x = 64
x = 16
AD = 16
Then, if we know AD, we can easily find AB. AB = AD + DB. AB = 24.
Lastly, we need to find AC. All of the other lengths on the big triangle have been double that of the smaller triangle, so 6 x 2 = 12. AC = 12.
#11.
BC will be parallel to DE if the proportions are equal.
AE / AB = AD / AC
1 / 5 = 2 / 11
These fractions are not equivalent, therefore BC and DE are not parallel.

Given: Right triangle ABC with altitude Line segment C D
Prove: a2 + b2 = c2
Triangle A B C is is shown. Angle A C B is a right angle. Altitude h is drawn from point C to point D on side A B to form a right angle. Line segment A D is labeled e, line segment D B is labeled f, side A B is labeled c, side B C is labeled a, and side A C is labeled b.
Complete the paragraph proof.
You can use the similar triangles formed by the altitude to write ratios for corresponding sides. Using ratios from the large and medium triangles, StartFraction c Over a EndFraction =
. This can be rewritten as
= a2. Using ratios from the large and small triangles,
= StartFraction b Over e EndFraction. This can be rewritten as b2 = ec. By substitution, a2 + b2 =
. You can then factor as a2 + b2 = c(f + e). From the large triangle, you know (f + e) =
. So, a2 + b2 = c2 by using substitution.
