You can solve this by setting up a proportion. You can put the number of items correct over the total number. and substitute the unknown number with x.
=
Cross-multiply
3400 = 100x Divide both sides by 100
34 = x
40 - 34 = 6

Answer: 75°
Step-by-step explanation:
Using the Base Angles Theorem, we can conclude that <ABC and <ACB are congruent. The angles of a triangle add up to 180 degrees so we can write this equation to solve for x:
x + 5 + 3x + 3x = 180
simplify
7x + 5 = 180
subtract 5 from both sides
7x = 175
divide each side by 7
x = 25
plug 25 in for x to find the angle measure
3(25) = 75
