Tanα=y/x
α=arctan(y/x), we are given the point (3.2, 6.2) so:
α=arctan(6.2/3.2)°
α=arctan(1.9375)°
α≈62.7° (to nearest tenth of a degree)
Answer:
x:y:z = 12:3:2
Step-by-step explanation:
x = 4y
2y = 3z ⇒ 4y = 6z
⇒ x = 4y = 6z
To find x:
Multiply the coefficients of y & z: 4 × 6 = 24
To find y:
Multiply the coefficients of x & z: 1 × 6 = 6
To find z:
Multiply the coefficients of x & y: 1 × 4 = 4
⇒ x:y:z = 24:6:4 = 12:3:2
Answer:
I am pretty sure it is 15.
Step-by-step explanation:
Answer:
50cm
Step-by-step explanation:
If the sides are consecutive odd integers,
Let the smallest side=y
The other sides are y+2 and y+4
The perimeter=144cm
y+y+2+y+4=144
3y+6=144
3y=144-6
3y=138
y=138/3=46cm
Therefore, the largest side of the triangle:
y+4=46+4=50cm
Therefore, the largest side of the triangle is 50cm
