The value of sec A = - √29/5

Step-by-step explanation:

As the terminal side of angle 'A' passes through (-5,2).

so the angle is in the 2nd quadrant.

We can find the length of the hypotenuse using the Pythagorean Theorem

$c^2\:\:=\:\left(-5\right)^2\:+\:2^2$

c^2=5^2+2^2

c^2=25+4

c^2=29

$c=\sqrt{29}$

As we know that

cos A = adjacent/hypotenuse

sec A = 1/cosA

= hypotenuse/adjacent

= √29/-5

= - √29/5

Therefore, the value of sec A = - √29/5

No option choices??!

Step-by-step explanation:

∠A = 70°, ∠B = 20°, ∠C = 100°

∠A = 90°, ∠B = 90°, ∠C = 90°
