Answer:
130°
Step-by-step explanation:
1. to connect point A and B (green line);
2. the 1st row: to define measure of the angle ABD (90°);
3. the 2d row: to define measure of the angle BAD in the ΔABD (65°);
3. the 3d row: to calculate measure of the arc BD using the formula m(arc BD)=2*m(∠BAD).
X^3 / X^5 = X^ -2
you have to subtract the exponents when you’re dividing
There's the graph
But the answer is x<9
X is all values below 9.
B
es un ángulo de 80
