Answer:

  • 103°

Step-by-step explanation:

  • <em>This is a cyclic quadrilateral (all vertices on the same circle)</em>

<u>Opposite angles are supplementary:</u>

  • ∠A +  ∠C = 180°
  • ∠B +  ∠D = 180°

<u>Find x:</u>

  • x + 5 + x - 7 = 180°
  • 2x - 2 = 180°
  • 2x = 182°
  • x = 91°

<u>Find D:</u>

  • ∠D = x - 14°
  • ∠D = 91° - 14° = 77°

<u>Find B:</u>

  • ∠B = 180° - 77° = 103°

Hey I’m struggling with number 13 so please show your work. Thx
Dafna11 [192]

Answer:

\frac{5}{12}

Step-by-step explanation:

Because \frac{3}{5} is being multiplied by S, we can divide \frac{3}{5} from both sides of the equation. This will give us:

\frac{1}{4}÷\frac{3}{5}

But, that looks a bit hectic. Instead of dividing, you can multiply by the reciprocal (which is essentially how to divide fractions). So, instead of \frac{1}{4}÷\frac{3}{5}, you get:

\frac{1}{4}×\frac{5}{3}

When multiplying fractions, remember you can just multiply straight across-- numerator x numerator, then denominator x denominator.

By doing that, you get the fraction \frac{5}{12}

\frac{5}{12} cannot be simplified any more, so S=\frac{5}{12} is your answer :)

I hope this helps

You decide to go to the candy store in the mall. You arrive at the store with $25 and then purchase 3 candy bars. You then buy a
Yuri [45]

Answer:

<h2> The cost of a candy is $1.25</h2>

Step-by-step explanation:

given the total amount at hand is $25

let the price of  candy be x

then the cost of 3 candy will  be 3x

the cost of a candy snake is $12.50.

balance at hand after the end of buying $8.75

the total expenses summed up must equal the initial amount at hand which is $25

the expression for the scenario is 3x+12.5+8.75=25

3x+21.25=25

3x=25-21.25

3x=3.75

x=3.75/3

x=$1.25

The cost of a candy is $1.25

Please help solve equation
gregori [183]
<h2><u>Solution</u> :-</h2>

Height of Eric = 6 + 1/6 feet

= 37/6 feet

Height of his brother = 5 + 3/4 feet

= 23/4 feet

Difference between their height :

= 37/6 - 23/4

= (74 - 69)/12

= 5/12

<u>Hence</u>,

Eric is 5/12 feet taller than his brother.
