Answer:
32 degrees
Step-by-step explanation:
The interior angles of a triangle always add up to 180.
Subtract the sum of 106 and 42 from 180.
180-(106+42)
180-(148)
32
x is equal to 32 degrees.
Answer:
89 2 irrational roots
Step-by-step explanation:
The discriminant Is b²-4ac when the equation is in the form
ax²+bx+c so in the equation
a=2 b=5 and c=-8
plug into the equation for the discriminant
so 5²-4(2)(-8)
25-(-64) 2 negatives make a positive so
25+64=89
since 89 isn’t a perfect square 2 irrational roots
Formula is (x-h)2+(y-k)2=r2
The answer to your question is: Yes, I can.
You haven't asked for the trigonometric expression, but here it is anyway:
The <u>cosine</u> function is the reciprocal of the secant function.
Answer:
b=22°
Step-by-step explanation:
because b+42=b+b-20
b+42=2b-20
b-2b=-20-42
-b=-22
b=22°
