Answer:

24, 66

Step-by-step explanation:

Complementary angles add to 90

x is the first angle

x+42 is the second angle

x+x+42 = 90

2x+42 = 90

Subtract 42 from each side

2x+42-42 = 90-42

2x= 48

Divide by 2

2x/2 =48/2

x = 24

The second angle is 24+42 = 66

Answer:

24° and 66°

Step-by-step explanation:

Angle 1 = x

Angle 2 = x + 42°

x + x + 42° = 90°

Subtract 42° from both sides and add

2x = 48°

Divide by 2

x = 24°

24° and 66°

Determine the area. Show your work. Round your answer to the nearest hundredth
vlabodo [156]

Answer:

54

Step-by-step explanation:

To solve this, you have to find the area of the square then the area of the triangle, and add them together.

To find the are of a square you multiply the base by the height.

Example: 6 × 6 = 36

To find the area of a triangle you multiply the base by the height and divide it by 2.

Example: 6 × 6 = 36

36 ÷ 2 = 18

Now we add both areas together.

Example: 36 + 18 = 54

2x^2=9-3x <br> Find the factors
d1i1m1o1n [39]

Answer:

x = -3, $ \frac{3}{2} $

Step-by-step explanation:

The given quadratic equation is: $ 2x^2 = 9 - 3x $

This can be written as: $ 2x^2 + 3x - 9 = 0 $

To solve a quadratic equation of the form $ ax^2 + bx + c = 0 $ we use the formula:

           $ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} $

Here, a = 2; b = 3; c = - 9

Therefore, the roots of the equation are:

$ x = \frac{- 3 \pm \sqrt{9 - 4(2)(-9)}}{2(2)} $

$ \implies x = \frac{-3 \pm \sqrt{81}}{4} $

$ \implies x = \frac{-3 \pm 9}{4} $

We get two values of 'x', viz.,

x = $ \frac{-3 + 9}{4} $ and $ \frac{- 3 - 9}{4} $

$ \implies x = \frac{6}{4} \hspace{5mm} \& \hspace{5mm} \frac{-12}{4} $

⇒ x = -3, 3/2

Since the factors of the quadratic equation is asked, we write it as:

(x + 3)(x - $ \frac{3}{2} $) = 0

because, if (x - a)(x - b) are the factors of a quadratic equation, then 'a' and 'b' are its roots.

Multiply (x + 3) and (x - $ \frac{3}{2} $ to see that this indeed is the given quadratic equation.
