Answer:
4√2 or 5.66
Step-by-step explanation:
x² + x² = 8²
=> 2x² = 64
=> x² = 32
=> x = √32 = 4√2 or 5.66
150/200×100%=75%
75% of 200 miles is 150 miles
0.25 ....decimal
3/4, 3:4....ratio
2/3 = 6/9....equivalent fractions, fractions
4/8 --> 1/2....equivalent fractions,fraction,simplest form
Answer:

Step-by-step explanation:
Suppose we have a triangle WXY whose internal angles are:



The sum of the measures of the angles must be 180°, thus:

Simplifying:
15x + 15 = 180
Subtracting 15:
15x = 165
Dividing by 15:
x = 11
Thus, the measure of angle Y is
