The sum of two consecutive integers is -239 find the two integers​
xenn [34]

Answer:

The two consecutive integers are -119 and -120

Step-by-step explanation:

As we know that these two integers are consecutive, that means that they will have a difference of 1. This means that we can find the two integers by adding 1 to the sum of -239 and then dividing it by two

1-239=-238\\\frac{-238}{2} =-119\\-119-1=-120

sergiy2304 [10]

hence, 27/2 =13.5km

speed=distance/time

time = distance/speed

time= 13.5/87 = 0.15517mm hr

0.15517×60 = 9.31minutes

A triangle has one angle that measures 23 degrees, one angle that measures 47 degrees, and one angle that measures 110 degrees.
blsea [12.9K]

Answer:

B) Scalene Triangle

Step-by-step explanation:

This must be a scalene triangle because:

If it were a right triangle, there would be a right angle so A is out

If it were an equilateral triangle, all 3 angles would be equal to each other so C is out

If it were an isosceles triangle, 2 angles would be equal to each other so D is out

A scalene triangle consists of angles that add up to 180 degrees, but none of them are equal to each other. Therefore B is right.

Use SOHCAHTOA

We are given the opposite of the angle and the hypotenuse. We can use the sine function to acquire the value of x°.

sin(x) = 7/13

Take the inverse sine on both sides by using a calculator to get:

x = 32.58°
