Find the exact value of secθ if cscθ=-4/3 and the terminal side of θ lies in Quadrant III.

Quadrant is III so, sign would be negative for Sec.
Now, we know, csc = H / P
So, H = 4, P = 3
Calculate for B, 
B² = H² - P²
B² = 4² - 3²
B² = 16 - 9
B = √7

We know, sec Ф = H / B = 4 / √7
We can write it as: -4√7 / 7  [ -ve sign for 3rd quadrant ]

In short, Your Answer would be Option B

Hope this helps!

Urgent help required with right triangle trig
mixas84 [53]

To find the area of a square with it's diagonal, there's actually a formula = (1/2)d², but here's how to do it if you don't have the formula:


The diagonal <em>c</em> separates the square into two of the same triangles. Therefore, we can apply Pythagorean Theorem


a²+b²=c² ← Since this is a square, a=b is a must

a²+a²=c² ← Combine like terms, and plug 26 in for c

2a²= 26² ← 26²=676, then divide 2 on both sides

a²= 676/2

a²=338 ← We can just stop here! Since <em>a </em>is a side of the square, therefore the area of a square = a²


Answer: 338 units²
