Answer:
Step-by-step explanation:
1) The sum of the angles on a straight line is 180 degrees. This means that
51 + b + 110 = 180
161 + b = 180
b = 180 - 161 = 19 degrees
2) Angle a = 60 degrees. This is so because they are vertically opposite angles.
3)The sum of angles in a triangle is 180 degrees. Therefore
angle a + angle b + angle c
60 + 19 + c = 180
79 + c = 180
c = 180 - 79 = 101 degrees
4) d + c = 180(sum of the angles on a straight line is 180 degrees). Therefore
d + 101 = 180
d = 180 - 101 = 79 degrees.
5) e + 51 + b + a = 180( sum of the angles in a triangle is 180 degrees). Therefore
e + 51 + 60 + 19 = 180
e + 130 = 180
e = 180 - 130 = 50 degrees
I’m pretty sure it’s positive so a upward one that looks like :u
Answer:
x = 1.5
Step-by-step explanation:
2(3x + 1) = 11
Distribute the 2 (use order of operations)
6x + 2 = 11
Combine like terms
6x = 9
Divide 6 from both sides
x = 9/6
Simplify!
x= 1.5
