THIS IS A RIGHT & isosceles triangle: A = 90. B = 45 THEN ANGLE C =45

THEN AB = AC = 4√2

APPLY PYTHAGORAS: BC² =AB² + AC²

===> X² = (4√2)² + (4√2)² ==>16.2 +16.2 = 64
X² 64 & X =√64 ==> X = 8

A destroyer on patrol spots an aircraft at an altitude of 10,000 ft and an angle of elevation of 20⁰. How far is the aircraft fr

Reika [66]

$sin= \frac{opp}{hyp} \\\\sin (20) = \frac{10000}{hyp}\\\\hyp= \frac{10000}{sin(20)} \\\\hyp= 29238 ft$

The aircraft is 29238 ft from the ship

Note: this is based on my assumption that we are looking for the hypotenuse.

If we are looking for the adjacent side, then the answer would be 27475 ft.

Without actually calculating, how much greater is the product 98×50 than the product of 97×50? Explain

erma4kov [3.2K]

The difference is 50 because you are multiplying 50, 98 times
So when you multiply 50, 97 times you are one 50 less than 98

Proof: 98x50=4900
97x50=4850
4900-4850=50
