Answer:
See explanation
Step-by-step explanation:
1. BK is an angle B bisector, then
(definition of angle bisector)
2. BM = MK, then
triangle BMK is isosceles triangle with base BK.
3. Angles adjacent to the base of isosceles triangle are congruent, then
Note that angle MBK is the same as angle CBK.
4. By substitution property,
5. By alternate interior angles theorem,
if , then
7m - 3n
m = 3, n = 2
Replace m and n with the appropriate numbers:
7(3) - 3(2)
Multiply both sides:
21 - 6
Subtract:
21-6 = 15
Exact form: -55/18
Decimal form: -3.05 repeating
Mixed form: -3 1/18
400? I’m confused what you’re asking me to do !
