Answer:
The shorter side should be cut to 23. 3cm
Step-by-step explanation:
The area of the required paper should be equal to the area of the paper available.
35×20=30(30-x)
700= 900-30x
30x=900-700
30x= 200
30x/30= 200/30
x=6. 66
∠P = 39º
∠Q=120º
∠R = 21º
m∠P+m∠Q+m∠R=180º (sum of ∠s in a triangle)
2x-3+6x-6+x=180º (substitution)
9x-9=180º (algebra)
9x=189º (algebra)
x=21º (algebra) (this is ∠R)
(2x-3)=39º (algebra) (this is ∠P)
6x-6=120º (algebra) (this is ∠Q)
1. Divide both sides by 2
2. Add 16 to each side
Answer x > -2
Answer: the answer is d
