Answer:
The required answer is
Therefore the number in green box should be 7.
Step-by-step explanation:
Given:
AB = 7√2
AD = a , BD = b , DC = c , AC = d
∠B = 45°, ∠C = 30°
To Find:
c = ?
Solution:
In Right Angle Triangle ABD Sine identity we have

Substituting the values we get


Now in Triangle ADC Tangent identity we have

Substituting the values we get

The required answer is
The slide costs $2 each time you ride. $15/2 = 7.5 so you can ride it 7 times.
Answer:
17. z=39/sin45=
y=39/tan60=
x=y/sin60=
19. x=
=6
y=2x=12
z=
Step-by-step explanation:
17.
because:sin45=39/z
so: z=39/sin45=
then: tan60=39/y
so: y=39/tan60=
last: sin60=y/x
so: x=y/sin60=
19.
because: tan60=
/x
so: x=
=6
then: sin30=x/y
so: y=x*sin30=2x=12
last: sin45=y/z
so: z=sin45*y=

If one flower needs 1/3 of a cup, nine times that amount would need 9/3. Simplified, this would be 3 cups.
