To find the length of the ladder, you need to do Pythagorean theorem.
50^2 + 30^2 = x^2
2500 + 900 = x^2
x^2 =3400
x= square root of 3400
58.31 OR 10 root34
To find the angle:
tan theta = opposite/adjacent
50/30 = 5/3
theta = tan inverse of 5/3
= 59.04
Answer:
18
Step-by-step explanation:
multyply both like 10 x 6 then 11 x 7 after that subtrac the numbers that you múltiple and you will get the answer
Answer:
17. z=39/sin45=
y=39/tan60=
x=y/sin60=
19. x=
=6
y=2x=12
z=
Step-by-step explanation:
17.
because:sin45=39/z
so: z=39/sin45=
then: tan60=39/y
so: y=39/tan60=
last: sin60=y/x
so: x=y/sin60=
19.
because: tan60=
/x
so: x=
=6
then: sin30=x/y
so: y=x*sin30=2x=12
last: sin45=y/z
so: z=sin45*y=
Answer:
yes, its a solution
Step-by-step explanation:
6(-2)+5(1)=-7
-12+5=-7 this is correct
2(-2)-4(1)=-8
-4-4=-8 this is also correct

Step-by-step explanation:
1. The first figure shows triangular prism. The volume of the triangular prism is

The base of this triangular prism is the triangle with the base of 7 cm and height of
cm (it is not seen).
The base area is

and the volume of the prism is

Just substitute the length of the height and calculate the volume.
2. The second figure shows square pyramid. The volume of the square pyramid is

The base of this square pyramid is the square with the side length of 4 yd.
The base area is

and the volume of the pyramid is
