Answer:
√33 cm
Step-by-step explanation:
Here,
b² = a² + c²
Because it is a right triangle
=> (17)² = (16)² + c²
=> 289 = 256 + c²
=> 289 - 256 = c²
=> 33 = c²
=> √33 = c
Hence,
height of triangle is √33 cm
Answer:
<u>Step-by-step explanation:</u>
Given: cos x = , x is in Quadrant 4
Use Pythagorean Theorem to find sin x:
8² + y² = 17²
y² = 17² - 8²
y² = 289 - 64
y² = 225
y = 15
→ sin x =
Use the double angle formula to find cos (2x):
Answer:
the answer is 4pi or 12.56637061
Step-by-step explanation:
the arc length equals 2pi x radius ( known angle (120) / 360 which equals 4pi or 12.56637061
Answer:
32
Step-by-step explanation:
16/20 reduces down to 2/5
set 2/5=x/80
cross multiply 160=5x
divide 32=x
check 2/5=32/80
32/80; 16/40; 8/20; 4/10; 2/5
yay 32 is the answer good luck :)
