Answer:
Step-by-step explanation:
Since these angles are supplementary, they add up to 180°.
Let's make an equation.
First we find the scale factor. It went from a 11 cm length to 16.5 cm length....so we have to find out what to multiply 11 by to get 16.5.
11x = 16.5
x = 16.5 / 11
x = 1.5
and since we multiplied 11 * 1.5 = 16.5, then we have a scale factor of 1.5...so we now multiply the height of 4 by 1.5.
So the new height is gonna be : 4 * 1.5 = 6 cm <==
Hey there!
To figure out the decimal of 7/33, just divide the numerator by the denominator. The numerator is the top part of the fraction. The denominator is the bottom part of the fraction.
So, 7 ÷ 33 = 0.212121.....
We can write this as 0.21 with a bar on top of 21. This shows that 21 is recurring.
Thank you! :D
