Since you have the hypotenuse (5) and the adjacent side (1.8) all you have to do is find out what squared times 1.8 squared equals 5 squared. the formula for this is a^2 + b^2 = c^2
Now to figure this out you can do 5^2 which equals 25.
Then you do 1.8^2 which equals 3.24. then you subtract the two and get 21.76.
if you find the square root of 21.76 you will get 4.6647.
4.6647 is the distance of how far up the wall the ladder reaches.
Answer:
NOR = 126.6
Step-by-step explanation:
one full circle would have 360 degrees
so we can make an equation that shows all of our angles adding up to 360:
NOQ + QOR + NOR = 360
we know that NOQ is 147.7
we know that QOR is 85.7
substitute these into our equation:
147.7 + 85.7 + NOR = 360
add like terms:
233.4 + NOR = 360
subtract 233.4 from both sides:
NOR = 126.6
Answer:
Step-by-step explanation:
Refer to attached for points
a) f(-1) = 3 as per graph
b) f(x) = 6
We add horizontal line through point y=6 to find intersections with the graph
Take x-values of those points. The points are x = -3, x = -2, x = 2
First, ensure that both sides are single fractions:

By cross multiply, we mean:
1. multiplying the numerator of the left hand side with the denominator of the right hand side.
2.multiplying the numerator of the right hand side with the denominator of the left hand side.
That is ..
a x d = c x b
