The expression to find the value of the final angle of the triangle will be 180° - 40° - α.
<h3>How to solve the triangle?</h3>
Your information is incomplete as the triangle isn't attached. Therefore, an overview will be given.
Firstly, it's important to know that the total angle in a triangle is 180°. A triangle has three sides. In this case, angle B is given as α.
Let's assume that another angle is given as 40°. Therefore, the expression to find the value of the final angle will be 180° - 40° - α

Answer:
the first two and last one
Step-by-step explanation:
Answer:
34/8 or 4 2/8
Step-by-step explanation:
6*8=48 48+5=53 =53/8
> (53/8) - (19/8) = 34/8 or 4 2/8
2*8=16 16+3=19 =19/8
You just change the whole numbers into fractions by multiplying it by the denominator, in this case 8. And then add your sum to the fraction part of the number to be left with just a fraction. To subtract, you just subtract the numerator, if the denominator is the same. In this case, it is, the denominator is 8.
