Answer: \Large\boxed{x=40^\circ}

Step-by-step explanation:

<u>Given information</u>

∡ 1 = 90°

∡ 2 = 50°

∡ 3 = x°

Total Angle = 180° <em>(Triangle angle sum theorem)</em>

<u>Given formula</u>

∡ 1 + ∡ 2 + ∡ 3 = Total Angle

<u>Substitute values into the formula</u>

(90) + (50) + (x) = (180)

<u>Combine like terms</u>

140 + x = 180

<u>Subtract 140 on both sides</u>

140 + x - 140 = 180 - 140

\Large\boxed{x=40^\circ}

Hope this helps!! :)

3x^2+42x+105=0 Find the solution<br><br>  <br>  <br> 0<br> 0
Nina [5.8K]

Step-by-step explanation:

I think we have to find the factors so

3x2 + 42x + 105

First we will multiply 105 by 3 = 315 then find factors of 315 which may add or subtract = 42

So 45 and 7

3x2 + 45x - 7x + 105

3x( x + 15) - 7(x - 15)

(3x - 7) and ( x - 15) are the factors

There is a problem please recheck the question
