any whole number containing 3 or more digits can be ÷ by 4 if the last two digits form a number that is divisible by 4 why?​
NARA [144]

Answer:

100 is always divisible by 4. Therefore it doesn't matter which number is up front.

the two other digits are important because there are 2-digit-numbers that are not divisible by four. "14" is not divisible by four, but "24" is.

34 isn't divisible, 44 is, 54 isn't.

So both digits will need to form a number that is divisible by 4, or it will not work.

Determine whether the given triangle has no solution, one solution or two solutions. Then solve the triangle. Round measures of
yuradex [85]

Answer:

The triangle has one solution. The remaining side c ≈ 4 and remaining angles B = 30°; C = 31°.

Option D is correct.

Step-by-step explanation:

if angle A is obtuse and if a > b then the triangle has one solution

We are given ∠ = 119° which is obtuse and side a= 7 and side b - 4 i.e 7>4 so, the triangle has one solution.

Finding remaining side c and ∠B and ∠C

Using Law of sines to find ∠B

a/sin A = b/sin B

7/sin 119° = 4/sin B

7 * sin B = 4 * sin 119

7*sin B = 4(0.874)

sin B = 3.496/7

B = sin^-1(0.4994)

B = 29.96 = 30°

We know that sum of angles of triangle = 180°

So, 180° = 119° + 30° +∠C

180° = 149° + ∠C

=> ∠C = 180° - 149°

∠C = 31°

Now finding c

b/sin B = c /sin C

4/Sin 30 = c/sin 31

4* sin 31 = c*sin 30

4*0.515 = c* 0.5

=> c =  4*0.515/0.5

c = 4.12 ≈ 4

So, Option D one solution; c ≈ 4; B = 30°; C = 31° is correct.
