Answer:
14.04°
Step-by-step explanation:
In this right triangle, we're seeking the measurement of an angle at the base of the triangle and we have the measurements of two of the sides (none are the hypotenuse) : the opposite one of the angle and the adjacent side.
The relationship between the two sides we have the measurement and the angle we are looking for is the tangent:
To find the angle we do an arctan on 0.25 and we get an angle of 14.04 degrees.
Answer:
155
Step-by-step explanation:
because he's skipping
Since both objects are assumed to have the same volume, matching the formulas we'll get:
π
h =
π
h
Having both <span>π and h at both sides of the equation, we can ignore them, so:
</span><span>
=
</span>
And clearing R, according to the equation rules, we'll get:
![\sqrt[2]{3 r^{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B2%5D%7B3%20r%5E%7B2%7D%20%7D%20)
= R
Do x divided by b on both sides and then add a on both sides. :)
The center is (0,0)
You are looking for a scale factor of 4..
Point a is found at (-3,1)
Point B (4,-3)
Point C (2,3)
Point D (-1,4)
Multiply each value by the scale factor of 4..
x:
Point A = -3 * 4 = -12
Point B = 4*4=16
Point C= 2*4=8
Point D=-1*4=-4
y:
Point A= 1*4=4
Point B= -3*4=-12
Point C= 3*4=12
Point D= 4*4=16
Your dilated points are:
A : (-12,4)
B : (16,-12)
C : (8,12)
D : (-4,16)
Hope this helps!
