Answer:
Step-by-step explanation:
8 must be the hypothenuse
4 and 7 are side
check Pythagorean Th. if works is a right triangle if not is not
8²=4²+7²
64 = 16+49
64 = 65 false
the lengths do NOT form a right triangle
COS(64°) = 3.2/x
multiply x to both sides to get COS(64°)x = 3.2
to get x by itself, divide 3.2 by COS(64°)
x = 3.2/COS(64°)
x=7.3
