Tan = opposite / adjacent
tan 74 = 24/7
Answer:
2/5, 8/20, 4/10,16/40
Step-by-step explanation:
40%
Percent means out of 100
40/100 = 4/10 = 2/5
Lets look at the choices
8/100 =4/50 =2/25 not equal
2/5 equal
8/20 = 4/10 =2/5 = equal
4/10 = 2/5 = equal
16/40 = 4/10 = 2/5 equal
Answer:
(6,1)
Step-by-step explanation:
12k + 1 = 8k - 2
4k + 1 = 2
4k = 1
k = 1/4
Hope this helps!
Law of cosine is :
c^2<span> = a^</span>2<span> + b^</span>2<span> − 2ab cos(theeta)
</span>so in case of right triangle , angle is 90 degree:
putting 90 degrees into formula:
c^2 = a^2 + b^2<span> − 2ab cos(90)
</span>As we know that:
cos90 = 0
c^2 = a^2 + b^2<span> − 2ab (0)
</span>c^2 = a^2 + b^2<span> - 0
</span>c^2 = a^2 + b^2 ( this is <span>pythagorean theorem ).
</span>So the above statement is True.
