What is the value of c?

1 answer:

7 0

The answer is 9.75 the steps are....
first simplify both sides so...
−1.6(2c+12)=12(−1.6)(2c)+(−1.6)(12)=12(Distribute)−3.2c+−19.2=12−3.2c−19.2=12
then add 19.2 to both sides because your trying to get the c by itself..
−3.2c−19.2+19.2=12+19.2−3.2c=31.2
and then finally divides both sides by -3.2 so that c will be by itself
AND THEN..you get 9.75

Please help. It’s a multiple choice question. I’ve my answer, but I’m not sure.

S_A_V [24]

Answer:

66 degree

Step-by-step explanation:

given:

angle FAB = 48 degree

angle ECB = 18 degree

in triangle HBC , angle H is also 48 degree degree since the line is parallel the connection between angle H and angle A is alternate interior angle and alternate interior angle are always equal.

so angle H = 48 degree

in triangle HBC

angle H + angle C = angle ABC (sum of two interior opposite angles are equal to the exterior angle formed)

48 + 18 = angle ABC

66 = angle ABC
