Answer:
Step-by-step explanation:
The interior angles of a heptagon add up to 5*180 = 900
So
x + 143 + 116 + 135 + 135 + 116 + 155 = 900 Add up the known angles
x + 800 = 900 Subtract 800 from both sides
x + 800 - 800 = 900 - 800 Combine
x = 100
Answer:
the answer is C
Step-by-step explanation:
Since both C & D are parallel, angle 2 is a corresponding angle to the angle of 108 degrees, so angle 2 is also 108 degrees
It’s C, y + 5 = 2(x - 4).
In y = mx + b form:
y = 2x - 13
Answer:
a) 800 square yards
b) 7200 square feet
Step-by-step explanation:
a) 40*20= 800 square yards
b) Each yard is 3 feet.
(40*3)*(20*3)=120*60=7200 square feet
