ANSWER
The value of theta in the second quadrant is,

EXPLANATION
The given trigonometric equation is

This implies that,

This implies that the principal solution is

and it is an angle in the first quadrant.
But the solution we are looking for is an angle in the second quadrant.
This is given by
Answer:
0, 3 , 8
Step-by-step explanation:
substitute n = 1, 2, 3 into the pattern rule
T₁ = 1² - 1 = 1 - 1 = 0
T₂ = 2² - 1 = 4 - 1 = 3
T₃ = 3² - 1 = 9 - 1 = 8
Gotta add a picture to show us what you want us to do.
Answer:
the length of the second rectangle is 33.75 in
Step-by-step explanation:
The computation of the length of the second rectangle is as follows
Let us assume the length of the second triangle be x
Now
The equation would be
4 ÷ 15 = 9 ÷ x
Now do the cross multiplication
4x = 15 × 9
4x = 135
x = 33.75 in
Hence, the length of the second rectangle is 33.75 in
