Answer:
BC = FE
Step-by-step explanation:
given ,
BA = FD and the measure of angle ABC = the measure of angle DFE
If we have BC = FE then according to the SAS criterion the two triangles are congruent
The answer after subtracting the following equation is x= -8/5
Step-by-step explanation:
- -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)
- subtracting eq 2 from eq 1 we get

Answer:
27; C; B; D
Step-by-step explanation:
1. B = 120 degrees, and C = 60 degrees. Q = 90 degrees, because B + C = 180 degrees, and the triangle BQC has angle B and angle C bisected. If B = 120 degrees, then the height is equal to 9 sqrt 3, which makes BC equal to 27.
2.C
3. B (You don't actually know if any of the sides are parallel.)
4. D
Answer:
12 300
Step-by-step explanation:
The way that I would do this, is first doing 7*300. That would result in 2100.
Next would be doing 7*12. Resulting in 84.
Finally you would add 2100 and 84 which is very simple just 2184.
If 300 looks like a tough number to multiply, just do 7*3 then add two 0's to the end.
