Hidden right triangle
28 feet tall (1 leg)
the piece that fell over is the hypotonuse
last leg is what we need to find
81-28=53
a²+b²=c²
a and b are legs and c is the hypotonuse
given
on leg is 28 and the hypotonuse is 53
th othe leg is b
28²+b²=53²
784+b²=2809
minus 784 from both sides
b²=2025
sqrt both sides
b=45
answer is 45ft
Answer:
(a, b, c) = (3, 12, 13)
Step-by-step explanation:
Due to Brainly's limitations with the equation feature, I can't show work...
If they have updates I'll 100% come back and edit this problem to show more work, but there's your answers.
Answer: x=3
Step-by-step explanation:
Use Pythagorean theorem.
a^2 +b^2 = c^2
4^2 +b^2 = 5^2
16 +b^2 =25
-16 from both sides
b^2 = 9
square root b^2 = square root 9
b = 3
b=x
x=3
Answer:
its moving uocan u feel it
Step-by-step explanation:
Perpendicular has slope that mutiplies to -1 to the other slope
for
ax+by=c
slope=-a/b
-1x+3y=9
-(-1)/3=1/3
1/3 times what=-1?
-3
y=mx+b
m=slope
y=-3x+b
find b
(-3,2)
(x,y)
x=-3
y=2
2=-3(-3)+b
2=9+b
mnus 9
-7=b
equaton is
y=-3x-7 or
3x+y=-7
