Answer:
m=10
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−7(2m−6)+21=−77
(−7)(2m)+(−7)(−6)+21=−77(Distribute)
−14m+42+21=−77
(−14m)+(42+21)=−77(Combine Like Terms)
−14m+63=−77
−14m+63=−77
Step 2: Subtract 63 from both sides.
−14m+63−63=−77−63
−14m=−140
Step 3: Divide both sides by -14.
-14m/-14=-140/-14
m=10
Answer:
6/sin 150 = 8 / sin B
Step-by-step explanation:
6/sin 150 = 8 / sin B
sin 150 = 1/2 so you cross multiply to get 6 sin B = (1/2) • 8
6 sin B = 4
sin B = 4/6
B = inverse sin (4/6) = 42º or 138º
But both of those add to 150 to go over 180 so there are no solutions.
Back in geometry, you had that the larger angle of a triangle is opposite the longer side, right? You can see that 150º can't be opposite 6 because then the angle opposite 8 would have to be larger than 150º which is impossible for a triangle.
