40 and 50,20 and 70

Step-by-step explanation:

complementary angles are angles that added equal to an angle of 90 degrees and it says they are not congruent so the two angles are diferent

Answer: 14

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

Consecutive even numbers would be {2, 4, 6, 8, 10, ...}

Let x represent the smallest number, then x + 2 is the middle number and x + 4 is the largest number.

1st number: x

2nd number: x + 2

3rd number: x + 4

1st number + 2nd number + 3rd number = Sum

(x) + (x + 2) + (x + 4) = 48

3x + 6 = 48

3x = 42

x = 14

1st number: x ⇒ x = 14

2nd number: x + 2 ⇒ 14 + 2 = 16

3rd number: x + 4 ⇒ 14 + 4 = 18

<u>Check:</u>

14 + 16 + 18 = 48 $\checkmark$

Find the values of x,y,z. This diagram is not a scale.

Serjik [45]

Important:
   The sum of the three angles inside
      every triangle is always 180°.

First, look at the left triangle alone.
Two of its angles are 46° and 58° . (46° + 58° ) = 104°
That leaves (180° - 104° ) = 76° degrees for the third angle.
The third angle in that triangle is 'x'.
   x = 76° .

At the point where 'x' and 'z' come together:
'x' and 'z' are a "linear pair".
Placed side-by-side, they form a straight line.
So (x + z) = 180° .
But x = 76°.
So z = (180° - 76°).    z = 104° .

Now look at the the skinny triangle on the right alone.
The angle at the top is 13°, and z = 104°.
(13° + 104°) = 117° .
That leaves (180° - 117°) = 63° for the third angle.
'y' is the third angle.
   y = 63° .

Ema ate 6 slices of pizza. She ate 3/4 of a entire pizza. How many slices of pizza were there in all?

Taya2010 [7]

Divide 6 by $\frac{3}{4}$

$\frac{6}{1}$ ÷ $\frac{3}{4}$

Change $\frac{3}{4}$ to a reciprocal

$\frac{6}{1}$ × $\frac{4}{3}$ = $\frac{24}{3}$

Simplify and your answer is 8
