Use the Pythagorean theorem:
The ladder will reach approximately 14.14 feet (exactly 10√2 feet) up on the building.
The answer is the fourth One
Answer:
The equation is x-18 + 8x = 180 (because they form a linear pair of angles.
Each angle measure:-
x-18 + 8x = 180
x + 8x = 180 + 18 (-18 becomes +18)
9x = 198
x = 198/9
x = 22
Angle 1 = x-18 = 22-18 = 4 degrees
Angle 2 = 8x = 8 * 22 = 176 degrees

Answer:
y={-5,-4,-5/2,-13/3}
Step-by-step explanation:
a.f(-2)=y=1/2(x)-4
substitute -2for x
y=1/2(-2)-4
y=-1-4
y=-5
b.f(0)
y=1/2(0)-4
y=0-4
y=-4
c.f(3/2)
y=1/2(3/2)-4
3/2-4
find the L.C.M=2
3/2-4/1
3-8/2
-5/2
d.f(-2/3)
y=1/2(-2/3)-4
-2/6-4
2 into itself 1 ,2 into 6 ,3
-1/3-4
find the least common multiple equal to 3
-1/3-4/1
-1-12/3
y=-13/3
Answer:
9,000 m
Step-by-step explanation:
1 km = 1,000 m
3 * 3 = 9 km
9 * 1,000 = 9,000 m
