Can someone help with easy math?

i hope this helps :)

Step-by-step explanation:

2.1.) A = bh = 3.2 * 1.8 ≈ 5.76

2.2) Using the formula  A = bh, solving for h, h = A over b = 44.4 over 7.4 ≈ 6

2.3) using the formula A = wl, solving for w, w = A over l = 38.25 over 9 = 4.25

2.4.) using the formula A = a^2, solving for a, a = = 4

2.5.) A = bh = 30 * 2 = 60

2.6.) using the formula A = bh, solving for h, h = A over b = 336 over 4 = 84

2.7.) using the formula A = bh, solving for b, b = A over h = 135 over 5 = 27

2.8.) A = wl = 18 * 30 = 540   250 * 2 = 500, 250 * 3 = 750    3

i dont know and i dont care for math bc it is a stupied subject

step-by-step explanation:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
