Screen measures 30 cm wide n 22 cm high what is the diagonal measure of the screen

Answers

Answer 1

Answer: I think you'd use the pythagoran theorem for this (a squared + b squared = c squared). So 30 squared plus 22 squared equals the diagonal measure squared. This is 900 + 484 = c squared. That's 1384. The square root of that is 37.

Answers

Answer:

V = 48 cubic units

Step-by-step explanation:

$V=b^(2) (h)/(3)$ Use this equation to find the volume

$V=6^(2) (4)/(3)$ Simplify the exponent

$V=36((4)/(3))$ Multiply

V = 48 cubic units

How do I find the missing side length?

Answers

adjacent side to angle 60º=2/3
opposite side to angle 60º=b
hypotenuse=a

cos 60º= adjacent side / hypotenuse
cos 60º=(2/3) / a
a=(2/3) / cos 60º=(2/3) / (1/2)=4/3

tan 60º= opposite side / adjacent side
tan 60º=b / (2/3)
b=(2/3)*tan 60º=(2/3)* √3=2√3 /3

Answer:
a=4/3
b=2√3 /3

subtract the to sides
