Answer:
1
Step-by-step explanation:
slope must be same because it is paralel
Answer:
28°
Step-by-step explanation:
soln
(x+3)°+(2x+3)°
x°+3°+2x°+3°=90°(beign complementary angles)
3x+6=90°
3x=90°_6
3x=84
x=84/3
x=28°
First find out how many more inches it needs to grow, 54-37.5; It needs to grow 16.5 more inches. If it grows 3 inches a year then you have to do 16.5/3; 5.5. It will take 5.5 or 5 1/2 more years to grow to 54 inches.
We are given with the sequence -20, -16, -12, -8. From this sequence, we can see that the arithmetic difference is +4, from -(-20 + 16). hence following the arithmetic formula of an = a1 + d *(n-1). Substituting, an = -20 + 4 *(n-1) where n is an integer
