Answer:

x=36

Step-by-step explanation:

the triangle is a right angle triangle divided into 2 at the angle representing 90°. Since the second triangle has two equal sides the angles therefore are also equal, hence

180°-72°=108°

then 108°÷2=54°. ( we divided because the angles are equal.

x=180°-90°-54°

x=36°

Find the distance between the points (2,2) (5,5)

Ugo [173]

Answer: root18

Step-by-step explanation:

A (2,2) x1=2 y1=2

B (5,5) x2=5 y2=5

D(AB) = root [(x2-x1)^2 + (y2-y1)^2]

= root [(5-2)^2 + (5-2)^2]

= root [3^2 + 3^2]

= root (9+9)

D(AB)=root18

How many real-number solutions does the equation have?

Nataly_w [17]

Answer:

Option b. Two solutions

Step-by-step explanation:

In order to find how many real number solutions the equation has we have to solve it

Given equation: -4x² + 10x + 6 = 0

taking 2 common from the equation

2(-2x² + 5x + 3) = 0

-2x² + 5x + 3 = 0

taking minus sign common from the above equation

2x² - 5x - 3 = 0

We will solve this equation by factorization in such a way that the sum of two factors is equal to -5x and the product is -6x²

2x² - 6x + x - 3 = 0

taking common above

2x(x-3) + 1(x-3) = 0

taking (x-3) common

(2x+1)(x-3) = 0

2x + 1 = 0

2x = -1

x = $\frac{-1}{2}$

x - 3 = 0; x = 3

the solutions are

$x=\frac{-1}{2},3$

Both values are real numbers, therefore correct option is b
