Answer:
Step-by-step explanation:
ASTC (I use a sentence to memorize: All Students Take Calculus):
Q1 - All functions are positive
Q2 - Sine is positive (Cosecant is positive as well) (all others negative)
Q3 - Tangent is positive (Cotangent is positive as well) (all others negative)
Q4 - Cosine is positive (Secant is positive as well) (all others negative)
Applying ASTC:
Secant is negative, so it can't be in quadrant 1, and quadrant 4.
Quadrant 2 - Sine and Quadrant 3 - Tangent are left.
Cosecant is positive so it can't be in quadrant 3.
Therefore, angle x is in Quadrant 2 or QII
Secant is hypotenuse / adjacent
5 = hypotenuse (hypotenuse is never a negative number)
-2 = adjacent
use pythagorean theorem to solve for opposite (bc tan = opp / adj)
tanx =
Answer:
A
Step-by-step explanation:
- f=1/2(a+b)×h
- 1/2(1.6+4)×2
- 2.8×2
- 5.6 since to round off 5.6 to the nearest tenth consider the hundredths' value of 5.6 which is 0. therefore the tenths value of 5.6 remains 5.6
Answer: -2 1/16
if you add it all together it should be 2 1/16
hoped this helped let me know if it did
