Equation with angles can some please answer

Mathematics
1 answer:
Gelneren [198K]3 years ago
5 0

Answer:

Step-by-step explanation:

Parallel lines. A & B are corresponding angles and corresponding angles are equal.

∠A = ∠B

8x - 8 = 5x + 25

Add 8 to both sides

8x - 8 + 8 = 5x + 25 + 8

8x = 5x + 33

Subtract 5x from both sides

8x - 5x = 5x +33 - 5x

3x = 33

Divide both sides by 3

3x/3 = 33/3

x = 11

∠B = 5x + 25 = 5*11 + 25 = 55 +25 = 80

∠B = 80°

Find the maximum value of c=4x+2y<br>2x+2y less than or equal to 10<br>3x+y less than or equal to 9
svp [43]

Answer: 14

<u>Step-by-step explanation:</u>

Step 1: Graph both equations to find the vertices (see attached):

  • The graph shows vertices at: (0, 0), (3, 0), (0, 5) and (2, 3)

Step 2: Input the coordinates of the vertices into the given function                  (c = 4x + 2y):

  • (0, 0):   4(0) + 2(0) = 0
  • (3, 0):   4(3) + 2(0) = 12
  • (0, 5):   4(0) + 2(5) = 10
  • (2, 3):    4(2) + 2(3) = 14

Step 3: Evaluate the value from Step 2 to find the maximum (largest).

  • the largest value between {0, 12, 10, 14} is 14

Brums [2.3K]
The two numbers are 3 and 5, because 3 is the product of 3(1) = 1, and 3(5) = 15. Which is divisible by 5. Both 3 and 5 are less than 10.

A criminal has escaped in a train wreck. The police believe he could have traveled no more than 7 mi in any direction from the w
adelina 88 [10]

Answer:

A = 153.94 sq mi

Step-by-step explanation:

In this scenario, we would be starting from the center point and searching the area of a square since the distance in every direction would the same 7 mi. This 7-mile distance would be our radius in this scenario. We now need to use the formula for the Area of a circle to calculate the search area. This formula is the following

A = \pi r^{2}

A = \pi 7^{2}

A = \pi 49

A = 153.94 sq mi

A total of 153.94 square miles must be searched.
