$138.78 is the rounded figure
Answer:
5.6 cm
Step-by-step explanation:
As you can see in the picture, there is a right triangle formed. The right angle is opposite the 6.5 cm side, so that is the hypotenuse, and the other sides are the two legs. The side we do not know in the right triangle is the height of the pyramid.
We know that a²+b²=c² for a hypotenuse c and two legs a and b in a right triangle.
height²+3.3²=6.5²
subtract 3.3² from both sides to isolate height²
31.36 = height²
square root both sides to isolate height
height = 5.6 cm
Using the range of [ 0 , 2π ]
The answer is 27.1 degrees. because 11.4+15.7 = 27.1.
Answer:
√28 = 2√7 or roughly 5.29
Step-by-step explanation:
work backwards! sqr of 28 = x^2 that equals 28
√28 = 2√7 or roughly 5.29
