Answer:
Side a = 10.44031
Side b = 10
Side c = 3
Angle ∠A = 90° = 1.5708 rad = π/2
Angle ∠B = 73.301° = 73°18'3" = 1.27934 rad
Angle ∠C = 16.699° = 16°41'57" = 0.29146 rad
Answer: 5(√3-1) unit.
Step-by-step explanation:
Since, By the below diagram,
For triangle BDC,
We can write,
⇒ 
⇒ 
⇒ 
⇒ 
Now, In triangle ADC,
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Pick 2 coordinates:
I choose first & last one (0,15) & (8-9)
Change in y is 24
(15--9 = 24)
Change in x is 8
(0 - 8) = - 8
24/-8 = - 3
So, slope = - 3
Hope this helps!
Answer:
4/9
Step-by-step explanation:
Ratio of boys = 4
Ratio of girls = 5
1. When illustrating ratios in fraction, you add the ratios
4 + 5 = 9
2. Next you put the boys ratio over the total ratio
4/9
3. Sometimes it can be reduced to a lower form eg. 5/10 can be reduced to
1/2.
Answer:
x=16/13
y= -9/13
Step-by-step explanation:
A: -4y=-x+4
B: y+3x=3
4B: 4y+12x=12
A+4B: 12x= -x+16
-----> 13x=16
x=16/13
-4y= -16/13+4
4y=16/13-4
y=4/13-1= -9/13
