Since the sine and cosine functions are cofunctions, they are complementary. The format for this is that sinx=cos(90-x). This works for secant and cosecant and tangent and cotangent. So, sin25°=cos65°.
X = 56°.
Based on the congruence statement, m∠L = m∠P; m∠M = m∠Q; and m∠N = m∠R.
Since m∠L = 72°, m∠P = 72°.
Since m∠N = x°, m∠R = x°.
We are given that m∠Q = 52°.
We can find the value of x by subtracting the given angles from 180:
180-(72+52) = 180-124 = 56°
Answer:
4/15
Step-by-step explanation:
Lets find a common denominator in order to find the total amount. There is a common denominator of 15 among 3 and 5. Therefore we will convert the fraction so they have the same denominator.
1/3 > 5/15
2/5 > 6/15
If Joy had read 5/15 of the book before reading at night, she already had the progress of being at 10/15 way through the book. At the end of the day, Joy had only 6/15 left of the book. To find the remainder, we subtract 10-6=4. This helps find the answer that Joy only read 4/15 of the book towards the end of the day.
751*5=3.755, which is the number of toys made in a week.
By multiplying 3.755 by 3, you find that the workers make 11.265 toys in three weeks.
