Answer: I think its D
Explanation:I sort of made a coordinate graph
The answer id 12 meters.divide -2x^2+20x+48 by 2 to get x alone and then umbrella
Answer:
B=45
Step-by-step explanation:
let the supplamentary angle of <A is <d
180-A=d
180-135=d
45=d
90+d+B=180
90+45+B=180
135+B=180
B=180-135
B=45
