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
