Answer:
82
Step-by-step explanation:
For this problem you would first round everything. 9.03 becomes 9, 19.87 becomes 20, 3.11 becomes 3 and 4.97 becomes 5. You then just do the problem. 9 + 20 = 29, multiplied by 3 makes 87, 87 - 5 = 82.

Just 2 equal angles are enough for the triangles to be similar .... The second triangle has the same angles as the first.
We know that the sum of the internal angles of a triangle is 180, so for the second triangle:
84,6 + 65 + X = 180
X = 180 - 84,6 - 65
X = 30,4 → same angle as the largest triangle
So we have AA~ similarity
Answer:
Ray AC and Ray BC
Step-by-step explanation:
Answer:
<1 = 55 degrees and <2 = 35 degrees
Step-by-step explanation:
Sum of complementary angles is 90.
<1 = 3x + 10
<2 = 4x - 25
3x + 10 + 4x - 25 = 90
7x - 15 = 90
7x = 105
x = 15
<1 = 3(15) + 10
<1 = 55
<2 = 4(15) - 25
<2 = 35
Answer:
71.875
use long division so the 5.75 goes on top of the 0.08
