Answer:

100°

Step-by-step explanation:

55°+25°+third angle=180°(by angle sum property)

80°+third angle=180°

third angle=180°-80°

third angle=100°

Answer:

The measure of the third angle of the triangle would be 100°.

Step-by-step explanation:

25 + 55 + x = 180

80 + x = 180

x = 180 - 80

x = 100

Step-by-step explanation:

Ok so you are already the number that y = 10 and z = -2. You will plug these number in the equation in order to find the answer. :-

y = 10 and z = -2

yz + z

10(-2) - 2

-20 - 2

-22

Hope this helps, thank you :) !!

A House needs to some maintenance one sink is dripping water every 10 minutes and the other sink is dripping every 12 minutes if

e-lub [12.9K]

Answer:

60 minutes

Step-by-step explanation:

We solve this question using Lowest Common Factor method

Find and list multiples of each number of minutes( 12 and 10 minutes) until the first common multiple is found. This is the lowest common multiple.

Multiples of 10:

10, 20, 30, 40, 50, 60, 70, 80

Multiples of 12:

12, 24, 36, 48, 60, 72, 84

Therefore,

LCM(10, 12) = 60

The number if minutes until they both drip again is 60 minutes

What is the area of a triangle whose side is 17 meters long

Lunna [17]

Answer:

125.141

Step-by-step explanation:

Assuming that this is an equilateral triangle, I am going to divide this triangle in half to get a right triangle.

17 is our hypotenuse

17/2 = 8.5, this is one of our legs

The other leg is our height, which we will find.

We use Pythagoras Theorem to find the height/leg: $a^{2} +b^{2} =c^{2}$

$17^{2} -8.5^{2} = 216.75$

$\sqrt{216.75}$ = 14.72243186

Now, we use another formula to find the area of the triangle: $\frac{Base*Height}{2}$

14.72243186 × 17 = 250.2813416

250.2813416 ÷ 2 = 125.1406708
