Answer:

35° , 55°

Step-by-step explanation:

Let one angle be x.

It's complementary angle is = (90 - x)°

According to the question ,

x - (90 - x) = 20

=> x - 90 + x = 20

=> 2x = 90 - 20 = 70

=> x = \frac{70}{2} = 35

Help please.......Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.
maxonik [38]

<u>Answer:</u>

  • The cost of 1 dozen doughnut is $6 and the cost of a dozen croissant is $10.

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

<u>We know that:</u>

  • D = Cost of a dozen doughnut
  • C = Cost of a dozen croissant
  • 10D + 7C = 130
  • 6D + 4C = 76

<u>Work:</u>

  • 10D + 7C = 130

        6D + 4C = 76

  • 4(10D + 7C = 130)

        7(6D + 4C = 76)

  • 40D + 28C = 520

        42D + 28C = 532

  • 40D - 42D = 520 - 532
  • => -2D = -12
  • => 2D = 12
  • => D = 6

<u>Now, let's substitute the value of D into the first equation.</u>

  • 10D + 7C = 130
  • => 10(6) + 7C = 130
  • => 60 + 7C = 130
  • => 7C = 70
  • => C = 10

Hence,<u> the cost of 1 dozen doughnut is $6 and the cost of a dozen croissant is $10.</u>

Hoped this helped.
