We know that ON = 80 cm and ∠ O = 37°.
cos 37° = 4/5
Adjacent / Hypotenuse = cos∠O
80/OP = cos 37°
80/ OP = 4/5
OP = 80 : 4/5 = 80 · 5/4 = 100
Answer:
d. 100 cm.
It is also a parallelogram, since it has two pairs of parallel sides. A square has two pairs of parallel sides, four right angles, and all four sides are equal. It is also a rectangle and a parallelogram. A rhombus is defined as a parallelogram with four equal sides.
Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x = 
Consider the left side

=
( multiply numerator and denominator by cos²x to clear fractions
=
← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven
Answer:
f(0) =4
f(6) =8
Step-by-step explanation:
f(0) = ?
We know 0 is less than 5 so we use the first part of the step function
f(0) = 0+4
= 4
f(6) = ?
6 is between 5 and 7 so we use the second part of the step function
f(6) =8
7.2 x 10 - 6 = 72 - 6 = 66
3.09 x 103 = 318.27
2.04 x 104 = 212.16
5 x 103 = 309
3.09 x 103 is the largest
