Answer:
Step-by-step explanation:
Area of triangle is 40 cm² correct to nearest 5cm² .
∴ Area of triangle = ( 40 ± 5) cm²
∴ upper bound for area of triangle is = (40 + 5) cm² = 45cm²
Base of triangle = 9cm
∵ area of triangle = 1/2 base × height
height = 2 × area of triangle/base
∴ upper bound for height of triangle = 2 × upper bound area/base
= 2 × 45/9 = 10cm
Hence answer is 10cm
Let
T = theta
Use the Law of Cosines to get
c^2 = a^2+b^2 - 2ab*cos(T)
<span>7^2 = 10^2+8^2 - 2*10*8*cos(T)
</span><span>49 = 164 - 160*cos(T)
-160cos(T) = 49-164
</span><span>-160cos(T) = -115
</span>cos(T) = -115/(-160)
cos(T) = 23/32
cos(T) = 0.71875 which rounds to 0.72
The final answer is C) 0.72
For this case we must represent the following expression algebraically, in addition to indicating its result:
"2 plus 9"
So, we have:
By law of the signs of the sum, we have that equal signs are added and the same sign is placed:
ANswer:
11
