Answer:

50°

Step-by-step explanation:

7x - 20 + 4x + 90 = 180

11x = 180 - 70

11x = 110

x = 10

ACB: 7(10) - 20 = 50

Answer:

50

Step-by-step explanation:

The sum of the angles of a triangle is 180

A +B +C = 180

90 +4x+ 7x-20 =180

Combine like terms

70+ 11x = 180

Subtract 70 from each side

70-70+11x = 180-70

11x=110

Divide each side by 11

11x/11= 110/11

x = 10

We want to find angle C

C = 7x-20

   = 7*10-20

   = 70-20

   = 50

Using the equation y = 3x – 5, what would the output be for an input of -4?
tino4ka555 [31]

Answer:

your question is really not clear but if you were to put the -4 in the Y then the answer would be X=1/3, if you plug in -4 for X and find Y then Y = -17

Step-by-step explanation:

plug in -4 in Y

-4=3x-5 add 5 on both sides,

1 = 3x divide 3 on both sides

1/3= x

plug in -4 in X

y = 3(-4)-5 multiply 3 and -4 = -12

y = -12-5 subtract the -12 and -5 = -17

y = -17
