50 is 10 times as much as 500
Answer:
A
Step-by-step explanation:
Given
= 13x
Multiply both sides by 2 to clear the fraction on the left side
x + 50 = 26x ( subtract x from both sides )
50 = 25x ( divide both sides by 25 )
2 = x ⇒ x = 2 → A
Answer:
Side known in ratio as 8: 32
Side known in ratio as 9: 36
Side known in ration as 10: 40
Step-by-step explanation:
We can add all the numbers in the ration to form the sum of all the sides, or also equal to perimeter. 8+9+10 equals 27.
So we can write 27x=108
x=4. Multiply 4 to 8, then 9, then 10. You get 32, 36, 40

Step-by-step explanation:
Answer:
1
Step-by-step explanation:
SinA+sin²A= 1
sinA=1-sin²A
sinA=cos²A
cos²A= sinA
Now,
Cos²A+cos⁴A=cos²A+(cos²A)²
Replace cos²Awith sinA
= sinA+sin²A
=1
cos²A + cos⁴A=1
Hope it helps :)
