Answer:

B) 60

Step-by-step explanation:

<u>Given:</u>

  • <A = 2x
  • <B = 60
  • <A and <B are supplementary angles (they add up to 180)

<u>Equation:</u>

<A + <B = 180

2x + 60 = 180

2x = 180 - 60

2x = 120

x = 60

What is an equation of the line that passes through the points 0,-2and 0,-5​
kherson [118]

Answer:

Any equation with a slope of 3 will work. You can use any y-intercept. This equation will work: y = 3x+1

Step-by-step-explanation:

3x says that the slope is 3, and on a coordinate plane, 2 is 3 places above 5, and since the slope is 3, it will go 3 spots up, and run into (0,2)

The following pairs of angle measures are the measures of 2 angles of 2 triangles. Which pair of triangles would NOT be simular
posledela
So to solve this question, just add up all the three angles (ignoring the second pair of the same angle)

So for example:

A) \sf{41+20+119=180}

So that equals to 180, and so it is not the answer choice since the triangles would have similar angles.

B) \sf{82+70+28= 180}
Also not the correct answer choice.

C) \sf{58+30+92= 180}
Also not the correct answer choice.

D) \sf{35+82+73=190}
So this triangle will not have similar angles, thus your correct answer! :)

\boxed{\sf{D ~which~is~35~and~82;~82~and~73~is~your~answer!}}
