Answer:
7.6 ft² ( to 1 dec. place )
Step-by-step explanation:
given 2 sides of a triangle and the angle between them, the area (A) is calculated using the formula
A =
ac sin B
= 0.5 × 4 × 13 × sin 17° ≈ 7.6
Answer: 9/10
Explanation:
3/4 divide by 5/6
= 3/4 x 6/5
= 18/20
= 9/10
43/6-7=43/6- 42/6=1/6
the answer is 1/6
check 43/6- 1/6= 42/6=7
Answer:
-0.5 or -1/2 or A
Step-by-step explanation:
180 degrees is Pi radians. To find out what the measure is in the paranthesees, divide 180 by 6 and get 30. Now multiply it by 7 to get 210. The question is asking for the sin(210). The sin of 210 is -0.5
