What is the measurement of angle a?

Mathematics

Illusion [34]3 years ago

Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25

Hence, angle a = 3(25) - 10 = 65°

Jan and two of her friends raised money by having a bake sale. They split the proceeds. If each person received $32.19, how much
AveGali [126]

Answer: 1. Equation =3x = M , where x = money each received and M= total money received.

2.total money from bake sale=$96.57

Step-by-step explanation:

STEP 1

Let the total money receive from proceeds be = M

and let the amount of money each receive after the split  = x

Since   Jan and her two friends raised the money together, the total proceeds will be calculated using the equation

x+x+x= M

3 x = M ---- Equation

STEP 2--- Solving

if 3 x= M

and x =mount of money each receive after the split=$32.19

Therefore total money from bake sale, M = 3x = 3 x 32.19 = $96.57

6. When one number is a multiple of the other number, that would make the first number the LCM. For example if your first number is 14 and the second number is 2, their first common multiple would be when 2 gets to 14.
2, 4, 6, 8, 10, 12, 14.
14 would be the first time the numbers are equal

5. The first thing to do to find out if 8 is a multiple of 56 is to divide 56 by 8 and see if it comes out to a whole number. 56/8=7
Since 7 is whole, 56 would be the LCM of 56 and 8.
8, 16, 24, 32, 42, 48, 56

I need help with this question
bearhunter [10]

Answer:

  7.28 miles

Step-by-step explanation:

Suppose the distance at closest approach is represented by x. Then the distance to the point of closest approach at the first sighting is ...

  d1 = x·tan(62°)

At the second sighting, the distance to the point of closest approach is ...

  d2 = x·tan(38°)

The difference of these distances is 8 miles, so we have ...

  d1 -d2 = 8 = x(tan(62°) -tan(38°))

Dividing by the coefficient of x, we find ...

  x = 8/(tan(62°) -tan(38°)) ≈ 7.2764 . . . . miles

The point of closest approach is about 7.28 miles from the landmark.
