Answer:
1:2
Step-by-step explanation:
convert kg to g
they both have a factor of 1100g
divide them both by 1100 to get 1:2
(12,1):12³+1³=1728+1=1729
(10,9): 10³+9³=1000+729=1729

Answer:
<h2>137°</h2>
Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° <em>subtract 223° from both sides</em>
m∠STU = 137°
