Answer:
A
Step-by-step explanation:
i used the process of elimination and got rid of answers that didnt make sense but based on the info given i could tell that x was 5 months because of where the point of 5 is on the graph
Answer:
C
Step-by-step explanation:
Since the triangles are congruent then corresponding angles are congruent
x is the angle between line with 3 strokes and 2 strokes
The corresponding angle is therefore ∠ C
∠ C = 180° - (63 + 29)° = 180° - 92° = 88°
Then x = 88 → C
Answer:
B: x=-1
Step-by-step explanation:
5x+6=1
5x+6-6=1-6
simplify
divide by 5 on both sides
x=-1
DEF = BAC : x = 15 <==
once u allign ur triangles, u will see that there is a scale factor of 1.5.
6 * 1.5 = 9
1.5(x - 5) = 15
1.5x - 7.5 = 15
1.5x = 15 + 7.5
1.5x = 22.5
x = 22.5/1.5
x = 15 <==
csc(2x) = csc(x)/(2cos(x))
1/(sin(2x)) = csc(x)/(2cos(x))
1/(2*sin(x)*cos(x)) = csc(x)/(2cos(x))
(1/sin(x))*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)*1/(2*cos(x)) = csc(x)/(2cos(x))
csc(x)/(2*cos(x)) = csc(x)/(2cos(x))
The identity is confirmed. Notice how I only altered the left hand side (LHS) keeping the right hand side (RHS) the same each time.
