From the Special Triangle Theorem, the hypotenuse is equal to the side lengtht times the Sqrt(2).
So hypotenuse H = xSqrt(2), x=H/Sqrt(2).
Using numbers, if H = 7, then x = 7/Sqrt(2) = 7Sqrt(2)/2 to rationalize it.
Resolving horizontally . Make forces to the right positive
resultant force = 70cos30-60cos60 = 60.62-60 = 0.62 lbs
resolve vertically
resultant force = 120 sin60 - 70 sin30 = 103.92 - 35 = 68.92 lbs in downward direction
magnitude of the ressultant forsse = sqrt(68.92^2 + 0.62^2) = 68.92 lbs
direction of the force = tan-1 (0.62 / 68.82) = 0.52 degrees east of south or
a bearing of
90 - 0.52 = 89.48 degrees
Answer:
A
Step-by-step explanation:
I think answer 5 should be ∠1 is congruent ∠2
Answer: C, 3500
Step-by-step explanation:
Each jump from year to year is multiplying by abt 1.6 (200/124 = 1.62, 322/200 = 1.61, etc.) so to find 1978 you'd multiply 2167 * 1.6
2167 * 1.6 = 3467.2 = closest to 3500
Answer:
189/16 inches squared
Step-by-step explanation:
When you are multiplying mixed numbers it is best to change them to improper fractions if it is easier for you.
2 1/4=9/4
5 1/4=21/4
If you simplify it, it will be 11.8125
Hope this helps! May I have brainliest I need to rank up.
