An outside angle is equal to the sum of the two opposite inside angles.
The two opposite inside angles from X are 63 and 46.
X = 63 + 46 = 109 degrees.
Answer:
A 846 square inches
Step-by-step explanation:
Use the net:
Rectangle 1: (21 in + 3 in + 21 in + 3 in) by 15 in.
Rectangle 2: 21 in by 3 in
Rectangle 3: 21 in by 3 in
total area = sum of areas of 3 rectangles above.
total area = (48 in * 15 in) + 2(21 in * 3 in)
total area = 720 in^2 + 126 in^2
total area = 801 in^2
Answer: A 846 square inches
Answer:x=53/6 and y=-55/6
Let the first number x
Second number b y
Sum of the numbers x+y=-1/3
x-y=18
Solve simultaneously
Using elimination method
We get
2y=-55/3
y=-55/6
Substitute for y in equation 1
x+55/6=18
x=18-55/6
x=53/6

gradient = -10
y intercept = 1
y = mx + b
y = -10x + 1
m = slope ; hence, slope = -10 in the eqn
y intercept = when x = 0
y = -10(0) + 1
y = 1
