Remember the rules of Sohcahtoa (Sine, cosine, tangent). For this problem we take the cosine of 38 because the labeled sides are the adjacent leg and the hypotenuse.
Cos(38)=79/x
Cosine of 38 is about 0.7880
0.7880=79/x
Next we multiply both sides by the denominator
(x) 0.7880=79 (x)
Then divide.
<u>0.7880x</u>= <u>79</u>
0.7880 0.7880
X=100.25
Hope this helped :)
This is just to easy the correct answer is A
Since he completes 10 minutes each day for five days, he completes 50 minutes.
The percentage of his total requirement would be 50/100 = 0.5 = 50%.
Answer:
3.6 pounds
Step-by-step explanation:
If 1 bottle weighs 3/5 pounds
the 6 bottles will weigh 6 x 3/5
= 18/5
ratio method :
1:3/5
6:x
since the ratios are direct we can cross multiply
18/5 = 1x
so the 6 bottles weigh 18/5 pounds or 3.6 pounds
The equation for area of a triangle is A= 1/2bh so a=1/2(12cm)(9.6cm)
