Answer:
Step-by-step explanation:
Sides opposite to equal angles are equal.
x = 8
Pythagorean theorem,
y² = 8² + 8²
= 64 + 64
y² = 128
y = √128
y = 11.31
Answer:
x = 16.6
Step-by-step explanation:
Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

which rounded to one decimal is
x = 16.6
3/4 also equals 12/16 so 12/16+5/16= 17/16 or 1 1/16

Step-by-step explanation:
Divide both sides by
