Step-by-step explanation:
20
opposite angles are equal
6x = 120
x = 20
Multiply 200 rolls by 70%
200 *0.70 = 140
The bowler should knock at least 6 pins down 140 rolls
So let's break this question down.
You need a bit of both, right? Well we need to calculate how many multiple choices we can do whilst having true/false questions, and not going over or under on points.
So, let's pick a random number, 5. So let's do 8x5, that equals 40.

Ok so now we have our number, 5 multiple choice questions.
The true/false questions should be easy, just do 3x20 and you get 60.
ANSWER: 5
