Answer:
(4) 0
Step-by-step explanation:
<u>Given:</u>
- cos²27°×cos²34°×...×cos²167 = ?
<u>Looking at the angles measures, they form series of: </u>
This is AP with the first term of 27 and common difference of 7
<u>We can see one of the terms of this AP is 90</u>
Since cos 90° = 0 ⇒ cos²90° = 0 and therefore given series equals to zero as one of the terms of multiplication is zero.
<u>So correct answer choice is</u> Option 4) 0
Answer:
Step-by-step explanation:
a triangle is 1/2 of the base x height. so the area of 4 triangles and the surface area of the base square is the total surface area.
Because people enjoy it. As of now, we’re quarantining so there’s not much else to do, yk?
X=is the number;
15%=15/100=0.15
15% of x=6.75
Then we can suggest the following equation:
0.15x=6.75
x=6.75/0.15
x=45
Answer: 15% of 45 is 6.75.
Answer:
40%
Step-by-step explanation:
5.75 · 0.40 = 2.3
5.75 - 2.3 = 3.45
