Answer:
Option C. cos70°
Step-by-step explanation:
we know that
If two angles are complementary, then the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle
Remember that
Tow angles are complementary , if the sum of their angles is equal to 90 degrees
so
If A+B=90°
then
sin(A)=cos(B)
cos(A)=sin(B)
In this problem we have
A=20°
B=90°-20°=70°
therefore
sin(20°)=cos(70°)
cos(20°)=sin(70°)
Based on the expression given, when it is solved, as a fraction in its simplest form it would be 558/1.
<h3>What is the fraction in its simplest form?</h3>
The expression, 62(9) can be rewritten as:
= 62 x 9
This is because the brackets denote that the number within the brackets should be multiplied by the number outside the bracket.
The solution is:
= 62 x 9
= 558
As this is an integer, it means that it has a denominator of 1. The fraction in its simplest form is therefore:
= 558 / 1

Remember that pi=180,
so 180/6=30, 30*5=150,
what's tan 150?
Remember that 150 degrees is in the 2nd quadrant, and this is tangent, so it means the answer must be negative, because tan 150= - tan 30, and -tan30=-√3/3.
Answer: -√3/3.
Answer:
x = 66
Step-by-step explanation:
The similarity ratio is DO/PA = 27/18 ➡3/2
So DT/PN ➡ x/44 = 3/2
132 = 2x divide both sides by 2
x = 66
