Sin 3pi/4 is angle 135 degrees or 45 degrees below 180 degrees. Hence it's opposite side is 1 and adjacent is 1, implying the hypothenus is sqrt(2). Hence
Sin 3pi/4 = 1/sqrt(2). Now multiply by sqrt(2)/sqrt(2) to get:
[1/sqrt(2).] * [sqrt(2)/sqrt(2)] = sqrt2)/2
Answer:
1 neither
2 neither
3 neither
Step-by-step explanation:
Answer:
red is 50% blue is 25%
Step-by-step explanation:
red is half the circle so it would be 50% and blue is half of a half so 25%
∠7 = 59°
∠6 = ∠2 = 36° ( vertical angles )
∠4 = 180° - ∠1 ( straight angle )
∠4 = 180° - 95° = 85°
∠7 = 180° - (85 + 36 )° ( sum of angles in a triangle )
∠7 = 180° - 121° = 59°
