Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
Answer:
a = (D+f) * g
Step-by-step explanation:
We want to isolate a
a/g -f =D
Add f to each side
a/g -f+f = D+f
a/g = D+f
Multiply each side by g
a/g *g = (D+f) * g
a = (D+f) * g
I believe the answer could be 13n.
