The question is about trigonometry solving two sides it is a right triangle hypotenuse is X left side is 20 bottom side is 21 i
need to find X and what degrees is angle A and B and C is already 90 degrees please help!!
1 answer:
Answer:
x = 29
Angle A = 46.4°
Angle B = 43.6°
Step-by-step explanation:
Since it is a right angle triangle, we can find x from pythagoras theorem;
x = √(20² + 21²)
x = √(400 + 441)
x = √841
x = 29
Using trigonometric ratios we can find angles A and B.
Opposite is 20
Adjacent is 21
Thus; opp/adj = tan B
20/21 = tan B
B = tan^(-1) 0.9524
B = 43.6°
Sum of angles in a triangle is 180°. Thus;
A = 180 - (90 + 43.6)
A = 46.4°

Let x be the first number each pair and y is the second of each
As you see 1x is 3y
And. 2x is 3*3y= 9y
3x = 3*3*3y= 27y
Last 4x =3*3*3*3y= 81y
So y = 3^x
I believe it 270.48 miles.
Zane climb up in 33 seconds
44•33 = 1452 m.
so, Zane start from 1313 + 1452 = 2765 m below the edge.
to reach the edge with constant speed, Zane need 2765/44 = 62.84 seconds
we can round it to 63 seconds
Answer:
m∠C = 107°
Step-by-step explanation:
there are 4 sides so we first need to find the total interior angle:
m∠C = 360° - 90° - 90° - 73°
= 107°
Answer:
12
Step-by-step explanation:
Use the pythagorean theorem (
). A and b are the two legs of the triangle, and c is ALWAYS the hypotenuse. Plug in the values for a and c
