<span>sin(theta) = 6/10 and theta is in the second quadrant. Use trigonometric identities to find the following quantities exactly.
---
sin = 3/5
=============
(a) cos(theta)
cos = sqrt(1 - sin^2) = -4/5 (negative in Q2)
-----
(b) sin(2theta) =
sin(2t) = 2sin(t)*cos(t) = -24/25 --> Q3
-----
(c) cos(2theta
cos(2t) = sqrt(1 - sin^2(2t)) = -7/25 (negative in Q3)
-----
(d) tan(2theta) = = sin(2t)/cos(2t) = 24/7 (+ in Q3)</span>
The length of each side of the equilateral triangle is 5x³ + 11x⁵
<h3>Calculating Perimeter</h3>
From the question, we are to determine the length of each side of the equilateral triangle.
An equilateral triangle has its sides <u>equal</u> to each other.
If the length of a side of an equilateral triangle is c,
Then, the perimeter, P, of the triangle is
P = 3c
From the given information,
P = 15x³ + 33x⁵
∴ 3c = 15x³ + 33x⁵
c = (15x³ + 33x⁵) / 3
c = 3(5x³ + 11x⁵) / 3
c = 5x³ + 11x⁵
Hence, the length of each side of the equilateral triangle is 5x³ + 11x⁵

Let total number of questions be x.
According to the question,
80% of x is 32
or 80/100 × x = 32
or x = 32 ÷ 80/100
or x = 32 × 100/80
or x = 32 × 10/8
or x = 4 × 10
or x = 40
<em>So</em><em>,</em><em> </em><em>total</em><em> </em><em>number</em><em> </em><em>of</em><em> </em><em>que</em><em>stions</em><em> </em><em>is</em><em> </em><em>4</em><em>0</em><em>.</em>
Answer:
B
Step-by-step explanation:
A right triangle must have one of its 3 angles equal to 90°
the only triangle with an angle of 90° is Triangle C
