Sagot :

Answer:

See below.

Step-by-step explanation:

1.

3x + 7 + 10x + 17 = 180  ( property of inside angles of 2 parallel lines)

13x + 24 = 180

13x = 180 - 24 = 156

c = 156/13

x = 12.

2.

As the triangle is a right triangle:

42.7 + N = 90

N = 90 - 42.7

= 47.3. degrees.

Answer:

for the first question it will be

Step-by-step explanation:

first make the equation from the numbers you see, (3x+7)+(10x+17)=180

the 180 comes from the lines that the equations are on both of the equations add up to 180 degrees,

then first add all like numbers [(3x+10x) + (7+17) = 180]= 13x+24=180

next subtract the non-variable number (forgot the term for it)

13x+24=180

     -24  -24

      13x=156

then divide the number in front of the variable

13x=156

13    13

x=12

then once you divide the answer is shown so you can put it in
