Answer:
Step-by-step explanation:
Remark
- x is opposite the 90 degree angle. It is the hypotenuse.
- 13 makes up the 57 degree angle. It is the side adjacent.
- The adjacent side and the hypotenuse define the cos(theta).
Formula
cos(theta) = adjacent side / hypotenuse
Givens
Theta = 57 degrees
Hypotenuse = x
Side adjacent = 13
Solution
- Cos(57) = 13 / x Multiply both sides by x
- x*cos(57) = 13 Divide by cos(theta)
- x = 13/cos(57)
- x = 13 / cos(57)
- cos(57) = 0.5446
- x = 13/ 0.5446
- x = 23.87
Answer:
77 is a composite number
Step-by-step explanation:
41 = 1 × 41
77 = 1 × 77 = 7 × 11
83 = 1 × 83
89 = 1 × 89
97 = 1 × 97
7.03 can be converted to 7 3/100.
.03 is the equivalent to 3 hundredths, we know this because it in the hundredths place.
Answer:
d
Step-by-step explanation:
Volume can be described as the total amount of space that is in a closed surface. this amount of space is usually three dimensional. Volume is usually measured in m³ or cm³ or in³
For example, the volume of a rectangular box given the following dimension : length - 3cm
breadth - 8cm
height - 10 cm
volume = length x width x height = 8 x 3 x 10 = 240 cm³
