Answer:
20.424
Step-by-step explanation:
Given words can be written as
Eight and eighty-eight hundredths = (8+)
=
= 8.88
Two and three tenth = (2+)
=
= 2.3
Now multiply them
i.e 8.88 × 2.3 = 20.424
So 20.424 is the Answer
you can just split the figure in 2 separate figures and them add the areas:
area rec. 1:
3m×3m= 9m²
area rec. 2:
3m× (2m+3m)
= 3m×5m
=15m²
total area:
9m²+15m²= 24m²
Answer:
Option (3)
Step-by-step explanation:
By applying cosine rule in the triangle ABC,
BC² = AC² + AB² - 2(AC)(AB)cosA
5² = 3² + 7²- 2(3)(7)cosA
25 = 9 + 49 - 42cos(A)
25 = 58 - 42cos(A)
cos(A) =
A =
A = 38.21°
A ≈ 38°
Option (3) will be the correct option.
