Step-by-step explanation:
Its maybe Find the area of the shaded portion sorry it’s wrong I tried my best
Answer:
1) d ≤ -12
2) x ≥ -25
Step-by-step explanation:
-2.5d ≥ 30
2.5d ≤ -30
d ≤ -12
10 - x ≤ 35
-x ≤ 25
x ≥ -25
They are congruent triangles,
Ratio of their corresponding sides is 5:25, =1:5 (look for hypotenuse)
so, 5x = 18-x (same manner for variable one)
18 = 6x
x=3
SO, OPTION C IS THE ANSWER.
