Can anyone help me?pls

b = 8.89, c = 11.96 and m∠B = 48°

Step-by-step explanation:

From the given triangle ABC,

We will apply sine ratio for angle A,

sin(A) =

sin(42)° =

sin(42)° =

AB =

AB = 11.96

c = 11.96

By triangle sum theorem,

m∠A + m∠B + m∠C = 180°

42° + m∠B + 90° = 180°

m∠B = 180 - 132

m∠B = 48°

By cosine ratio of angle A,

cos(A) =

cos(42)° =

AC = AB.cos(42)°

AC = (11.96)cos(42)°

AC = 8.89

b = 8.89

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

x=5
