Answer:
Measure the angels to find and acute angle, right angle, or obtuse angle
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
12kilometers
If 2cm=8km, 1cm=4km
Multiply both by three and you get that 3cm=12km
Answer:
19
Step-by-step explanation:
Cause it’s angle on a straight line which is equals to 180
Answer:
