Answer:
y= 18
42°
x=60
60°
Step-by-step explanation:
because of vertical angles theorem, 2y+6=8y-102
add 102 to 6
2y+108=8y
subtract 2y from 8y
108=6y
y= 18
now plug in to each equation for angles
2(18)+6= 42°
8(18)-102= 42°
now I dont think you can solve for x and y in an equation. 3x=180
divide 3 from 180
180/3 = 60
x=60
plug 60 into 3x=180 and get 180°.
angles for x are 180°
if I'm incorrect on the X value someone please correct me.
I hope this helps!❤
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
