Answer:
tan(35) = x/20
20(tan(35)) = x
14.0 in. = x
14.0 inches
Step-by-step explanation:
use trigonometry to figure out the height.
Is john 16?
Since samantha is 48 and she is 2 times older than me, that means im 24 (48/2) and since 3 times older than john that means 48/3= 16. John is 16
Answer:
True
Step-by-step explanation:
In order to calculate this, we simply need to replace the variable c with the value of -8 and solve the inequality.
-9c >= 63
-9 * -8 >= 63
72 >= 63
Since both values are negative the product will be positive. This product is 72 which is in fact greater than 63, thus making the statement True
Answer:
The bottom one ....see below
Step-by-step explanation:
Using reference angle of pi/8 and half angle trig identity:
cos ( angle/2) = -sqrt (1 + cos (angle) /2)
cos ( pi/4 / 2) = - sqrt (1+ cos ( pi/4)/2)
<u> cos (pi/8)</u> = - sqrt (1 + sqrt (2) / 2)
= - sqrt (1 + sqrt 2) / sqrt 2 rationalize the denominator
= - sqrt ( sqrt 2 + 2) / 2
re arrange to
- sqrt ( 2 + sqrt2) / 2 the fourth answer
