Answer:
m∠BEF = 65.3°
Step-by-step explanation:
Given:
m∠DEB = 27.2,
m∠DEF = 92.5
Required:
m∠BEF
SOLUTION:
Since B is the interior of ∠DEF, it means ∠DEB and ∠BEF are adjacent angles that make up ∠DEF. And they share the same side, BE.
Therefore:
m∠BEF + m∠DEB = m∠DEF (angle addition postulate)
m∠BEF + 27.2 = 92.5
Subtract 27.2 from each side
m∠BEF + 27.2 - 27.2 = 92.5 - 27.2
m∠BEF = 92.5 - 27.2
m∠BEF = 65.3°

Answer:
2s-4r+3
Step-by-step explanation:
1st I combined like terms for 4r-8r
2nd I used the associative property of equality with -4r-3+6s+(-4s+6) into
-4r-3+6+(-4s+6s)
3rd I combined like terms for -4s+6s
4th I combined like terms for -3+6
