The answer is b just take the decimal off and subtract
Answer:
4
Step-by-step explanation:
3x+3=15
3x=15-3
3x=12
x=4
Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2
Since cosa=adjacent side / hypotenuse
cos45=1/√2
We can rationalize the denominator by multiplying numerator and denominator by √2
√(2)/2
or if you prefer: √(1/2)
Answer:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
Q = 30, R = 80, P = 50
Step-by-step explanation:
in triangle PQR, <P - <Q = 20 degrees, <Q - <R = 50 degrees, find <P, <Q, <R
R = Q
+50, 80=30+50
P = Q
+
20, 50=30+20
Q = 30, R = 80, P = 50
Answer: 3
Step-by-step explanation: To solve for A we need to get it by itself by doing the inverse of mulitplication, which is, division. 27/9=3, so a=3.
