<em>16/9</em>
- Step-by-step explanation:
<em>1,7777777777777 = </em>
<em>= 1,(7)</em>
<em>= (17 - 1)/9</em>
<em>= 16/9 </em>
390% that's the percentage enjoy
CB is 10.392...
(root 12^2 - 6^2 = 6root3)
CB is now the opposite
CD = hypotenuse
Hypotenuse + opposite = SOH - sin
Sin55 = o/h
sin55 = 6root3/h
x h, then ÷ sin55
H = 6root3/sin55
H = 12.686...
To 3 s.f CD is 12.7cm
(root = square root)
Hope this helps!
Answer:
x = 34
Step-by-step explanation:
The angles x + 12, 100, and x add up to a straight angle, so the sum of their measures is 180°.
(x + 12) + (100) + (x) = 180
x + 12 + 100 + x = 180
2x + 112 = 180
2x = 68
x = 34
