To find decimal form, you first have to change 1/4 into a decimal. That equals 0.25. The percentage would be 6.25%. Now to find the decimal equivalent, move the decimal two places to the left. To fill in the one missing place, add a zero before the 6. Therefore, 6 1/4% is equal to 0.0625 in decimal form.
Answer:
48 + 18√13 cm²
Step-by-step explanation:
HC = BC/2 = 4m/2 = 2 m
AC = √AH² + HC² = √9 + 4 = √13
A = 2×A(ABC) + 2×A(ACFD) + A(BCFE)
= 2×AH×BC/2 + 2×AC×CF + BC×CF
= 2×3×4/2 + 2×√13×9 + 4×9
=12 + 18√13 + 36
= 48 + 18√13 cm²
I think it’s supplementary angle
The slope is 2.
hope I helped.
