Answer:
15 and a half
Step-by-step explanation:
Bud=17
17-(2/3 x 2)=? 2/3=0.67%, 0.67% of 2=1.34
17- 1.34= 15.66
For the first problem, the triangle is equilateral. This means that all three sides will have the same length. So you need to find a value for x that makes all three of those statements equivalent. I believe you could find it using a system of equations... but it’s been a while so don’t quote me on that.
For the second, ce and de are equal. Set them equal to each other and solve for x. Then plug that x value back into the side lengths.
<h3>Answer: 133 cm</h3>
============================================================
Explanation:
I'm going to relabel the figure as triangle ABC.
As the instructions mention, we'll use the law of cosines to find the missing side.
- side a = 147
- side b = 166
- angle C = 50 degrees
Use these facts to find side c
c^2 = a^2 + b^2 - 2*a*b*cos(C)
c^2 = 147^2 + 166^2 - 2*147*166*cos(50)
c^2 = 17794.393497
c = sqrt(17794.393497)
c = 133.395628
c = 133
X will equal 4 because 4^2=4*4 which equals 16
