Answer:
C
Step-by-step explanation:
In a right triangle, the side opposite the right angle is the largest side as the right angle represents the largest angle in the triangle. Therefore, as 17.5 is opposite the right angle, we can say that AB²+10²=17.5², and √(17.5²-10²)=AB = 14.4
Using sohcahtoa, we can establish that
sin(∠C) = opposite/hypotenuse = 14.4/17.5, and
arcsin(14.4/17.5) = ∠C = 55°
Because the angles in a right triangle add up to 180 degrees, we can say that ∠A+∠B+∠C = 180°, so ∠A + 90 + 55 = 180 and ∠A = 35°
Answer:
Irrational
Step-by-step explanation:
This answer will always irrational because for example if have 2 square root 3+4 then it would be irrational if you add them together because you wouldn’t be able to put that in a fraction
Answer:
The number of days
Step-by-step explanation:
Since the person sold at saturday and sunday, and it says x represents the number of books sold and 3 represents that 3 more was sold in sunday. Therefore we need to know how much it sold throughout the weekend, so we need to know the number of days to calculate, thus 2 must represents the number of days.
Step-by-step explanation:
neither of the ones shown have an area of 9.
do you have another choice with a base of 6 and height of 3 or vice versa? because that would be an area of 9
