Answer:
Yes, we can measure waves with instruments. We can also use math.
Answer:
x = 9
y = 3
Step-by-step explanation:
2x + 2y = 24 is the same as x + y = 12
using substitution, x = 12-y
12 - y = 3y
12 = 4y
y = 3
x = 3(3)
x = 9
They're irrational numbers, so they can't be exactly written down.
Rounded to the nearest thousandth, they are
- 15.280
and
- 0.720 .
Step-by-step explanation:
Here. ...the sum of interior angle of triangle is 180° so...
90° + 43° + y = 180°.
133° + y = 180°
y = 180° - 133°
y = 47°
Answer:
z=31°
Step-by-step explanation:
32°+117°+z=180°{ sum of angle of triangle}
z=180-149
z=31°
