Rotate the degrees until the angle is between 0 and 360.
-1035 +360 = -675
-675 + 360 = -315
-315+360 = 45
Now you have sin(45)
The value of sin 45 = √2/2
The value of sin(-1035) is √2/2
Answer:
The value of b is 21
Step-by-step explanation:
29=√20^2+b^2
or, 29=√400+b^2
or, 841=400+b^2
or, 841-400=b^2
or, √441=b
b=21
Use the pythagorean theorem.
Answer:
x=27
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
90 + x+23 + x+13 = 180
Combine like terms
126 +2x = 180
Subtract 126 from each side
126-126 +2x=180-126
2x =54
Divide by 2
2x/2 = 54/2
x = 27
