Answer:
C is correct
Step-by-step explanation:
y = cos(0.4x)
Let
Haru's number ---> x
<span>Leon's number ---> (3/8)x
</span>so
ratio of
<span>Leon : Haru = (3/8)x : x </span>
<span>= 3/8 : 1 </span>
<span>= 3 : 8
</span>
the answer is
3 : 8
1. 2n + 2*5 =2
2. 2n + 10 = 2
3. 2n = 2 -10
4. 2n= -8
5. n = -8/2
6. n = -4
Since, it is given that the pentagon ABCDE is congruent to pentagon FGHIJ.
By being congruent, the corresponding angles and sides are equal.
Therefore,
,
,
,
,
.
By using 
So, 
Therefore, the measure of angle 1 is 100 degrees.
So, Option B is the correct answer.
