Answer:
x is 48.59
Step-by-step explanation:
sin(x)=0.75------problem
1)you need to get x alone, so inverse
x=sin^-1 (0.75)
2)plug into calculator!
This is subtraction an the answer would be 6
Answer:
x1 = -3 x2 = 3
Step-by-step explanation:
Answer:
It would be triangles A & C
Step-by-step explanation:
This is because all of the angles within triangle add up to 180, with this, you can do the following to find the missing sides:
Tri A:
180-110-30 = 40
Tri B:
180-45-30 = 105
Tri C:
180-110-40 = 30
When you do this, look at the angles of the triangles. You see that Triangle A with the angles 110, 30, and 40 all match with those seen in Triangle C.
Therefore, the two triangles are congruent.
