X by its self is always 1x
1x+8=-15 you have to get rid of 8 by subtracting on both sides
1x=-23 now get rid of 1 by dividing on both sides
x=-23
If Triangle ABC is similar to triangle DEF, then ∠A is congruent to ∠D, ∠B is congruent to ∠E, and ∠C is congruent to ∠F.
If ∠E = 40°, then ∠B = 40°.
There are 180° in a triangle. If ∠A = 35° and ∠B = 40°, then ∠C = 180° - 35° - 40°.
180 - 35 - 40 = 105°
m∠C = 105°
Answer:
You flip one and multiply them
for the red it is 5out of 15 or 3/5
and for the blue it is 4/15
and if it wants it together it is 9/15 or 3/5
hope this helps
