Molly's equation
15x + 10 = 100
-10 -10
15x=90
/15 /15
x=6
Maddie's equation
15x - 10 = 100
+10 +10
15x=110
/15 /15
x=7 1/3
MADDIE IS RIGHT
this is because she said 7 ans=d you cannot buy 1/3 of a shirt.
give the guy under me the 5 stare and a thanks this is his answer
Answer:
5
Step-by-step explanation:
-2 - (-7)
you have to do the opposite of the sign and switch the last number from neg to pos
You are given the side adjacent to ∠B and you want to find the length of the side opposite. The trig ratio that relates an angle to adjacent and opposite sides is ...
... tan(∠C) = Opposite/Adjacent = (AB)/(BC)
Multiplying by BC gives
... AB = BC×tan(∠C) = (14 ft)×(√3) ≈ 24.2 ft
Angle A and D are similar
Angle B and E are similar
Angle C and F are similar
So this means they have congruent angles, meaning whichever angles are similar the angles will also be similar.
So since angle A is 62 degrees, angle D is 62 degrees too.
Since angle E is 80 degrees, angle B has to be 80 degrees as well.
All triangles add up to 180 degrees, so to find the angle measure of angle C and F, do:
180-(62+80)
180-142
= 38 degrees
So angles C and F are 38 degrees
Conclusion:
angles A and D: 62 degrees
angles B and E: 80 degrees
angles C and F: 38 degrees
