Answer:

Thus, the value of x in the given triangle is 55°

Step-by-step explanation:

Given - Dimensions of triangle and angles

of triangle

Find - Value of x

Solution - The value of x in the given triangle is 55°.

As per the given dimensions of the triangle, the triangle is isosceles. This states that the neighbouring angle will be x° as well.

Thus, the mathematical expression of all the angles of a given triangle will be -

x + x + 80 = 190

2x + 80 = 190

2x = 190 - 80

2x = 110

x = 110/2

x = 55°

Answer:

1)  (-y^2-4y-8+4y^2+6y-3)

2)  32x^5y^4z^2

3)  x^3-9x^2+14x+24

Step-by-step explanation:

Given the expression we have to simplify the expression

1)   (-y^2-4y-8)-(-4y^2-6y+3)

⇒ (-y^2-4y-8+4y^2+6y-3)

Combining like terms, we get

⇒ 3y^2+2y-11

2.)    (2x^2y^3z^2)(4xy.4x^2)

⇒ (2x^2y^3z^2)(16x^3y)

⇒ 32x^5y^4z^2

3.)   (x-4)(x^2-5x-6)

⇒ x^3-5x^2-6x-4x^2+20x+24

⇒ x^3-9x^2+14x+24

Using PEMDAS
P = 1x1+9x(0.01)+1x(0.001)
E = no change
M = 1+0.09+0.001
D = no change
A = 1.091
S = no change
final answer is 1.091

Sara ran 10km in 2.5 hours. Katerina ran 7.5 km in 2 hours. Candice ran 9.5 km in 2.25 hours. Who had the fastest average speed?
Arisa [49]

10 km ÷ 2.5 hours = 4 km/h — This is Sara's record

7.5 km ÷ 2 hours = 3.75 km/h — This is Katerina's record

9.5 km ÷ 2.25 hours = 4.2 km/h — This is Candice's record

Therefore, the answer is Candice had the fastest average speed.

arron takes his dog for a walk afer school, he walks 5 blocks east and then 4 blocks north. if he was able to take a direct rout
nlexa [21]

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where a and b are 2 legs of the triangle, and c is the hypotenuse, aka the longest side of any triangle:

a^2+b^2=c^2

We know a and b and want c

4^2+5^2=c^2

16+25=c^2

41=c^2

Therefore, c is approximately 6.403
